Misconceptions about knives

There are a lot of misconceptions about knives and blades.

One thing I find frustrating is that people often believe purely aesthetic decision choices, or features that might improve everyday quality of life for the weapon, actually make a knife more lethal.

In reality, two pointy metal objects with a sharp edge, of a similar size and shape, will have a very similar injury profile. If you stab someone to the neck with a butterfly knife, it will have the same practical effect as the blade on a pair of scissors.

Ultimately, this means two things:

  1. All sharp, pointy metal objects are lethal and must be treated that way; police, for example, are equally justified in using lethal force whether the subject is armed with a balisong or a pair of scissors.
  2. Banning particular kinds of sharp, pointy metal objects does not make the street safer, because they can be substituted for other sharp and pointy metal things which are equally lethal (balisong -> kitchen knife or scissors for example).

Kitchen knives are used in many fatal stabbings. They are just as effective as knives “designed” for killing.

Most knives are small, simple, easy to use, easy to conceal, fast to deploy, and very effective. The qualities many people worry about are superfluous to their function, or merely improve quality of life and comfort. Much of it is about style and aesthetic concerns.

Preventing Death In CustodyDownload

Some excellent feedback from a paramedic in the Reddit thread for this video.

How to prevent death in custody – positional asphyxiation, excited delirium, best practice methods and more [28 minutes]
byu/PaperworkPTSD inProtectAndServe

Text wall incoming: I would like to add some comments here. I am a paramedic in the urban U.S., so I do not know the training or the things that are taught to LEO, but I would offer some alternative perspective. This was a well thought out video, but I would also add some tools/methods that I have used/seen used to help expedite the process.

  1. This was a very thoughtful video, and succinctly emphasizes your position when dealing with psych/overdose/mental health patients in delirium. Which is, in between a rock and a hard place. These people need medical evaluation and intervention, which often Law enforcement is ill equipped to provide. It then becomes a matter of how quickly can you get the ambulance to you to assist. Normally, EMS will not go into active scenes because our defense profile is much less robust than yours. But getting on the radio quickly will ensure that once you have compliance, or even 60-75% compliance, the ambulance is already on the way. Even on your way to the call, if your call notes describe someone who will need an evaluation, just start us. If we get pissy when we get there and its not super serious, thats on us and I hope you dont have that kind of working relationship with your EMS agency, because thats a junk attitude for us to have. Better an easy evaluation and refusal than a cardiac arrest.
  2. There were many clips in this video that show prone positioning, and the continued struggle. OP did a good job of alerting to the cycle of “movement/restraint” that so many of us get into, and how that leads to bad outcomes. If you have to prone someone, then do that, but if the ambulance is coming, there are also safer ways to restrain once we get onscene. The primary intervention is sedation. We all want that person to stop thrashing, so we have to get our drugs onboard. However, once we get there, you now have force multipliers. Do not shy away from using us as help to restrain while the medication takes effect. Limb joint restraint, waist and shoulder control can all be had while prone if need be, and take pressure off the chest. And to be clear, even pressure on the lower back where the abdomen would be can cause asphyxiation, by not allowing proper expansion of the diaphragm.
  3. Please continue to be observant. Many times, once EMS arrives on scene, the police tend to lower their security posture because “EMS is onscene” and it is a medical patient. But I have been stabbed by a patient with APD standing next to her because they were talking to themselves while I was doing my thing. Anyone who needed EMS and is hyperactive is by definition unstable. Please be ready to jump back into the fight. We may also have to use you as our own force multipliers.
  4. The pathophysiology of these patients is unpredictable. The reason why these people suddenly arrest with seemingly no pressure is because of whats happening inside the body. Extremely simplified basically, the drugs/psychosis/etc are causing an unregulated adrenaline dump, giving them their super strength, or their resistance to control techniques and the like. Once their body uses up all of their adrenaline, they’re going to arrest. Our sedation medications add onto that effect, especially if we have to give a double dose because of their extreme adrenaline dump. Which means that predicting when they stop fighting is a nonstarter. Once you go hands on, at any point in time, they may run out of energy and go into arrest, ems or no ems assistance. Look for the signs, and act appropriately.
  5. Thank you OP for not saying that Ketamine from paramedics kills these people.

Sorry for the long wall, I’ve been a paramedic for 11 years-ish now and teach both LEO/EMS team patient control, and basic resuscitation to the police I work with. You guys got the short end of the stick in dealing with these patients, and I dont want any of these cases to happen to you guys.

Scissors were used during infamous fatal stabbing in Fortitude Valley

A jury has been told Seyram Kwami Djentuh stabbed Lauie Tagaloa in the neck with scissors he bought minutes earlier for $3.90.

The two groups had been “eyeing each other off” and were keen for a fight, before Tagaloa punched a man in the other group and stomped at his head.

The confrontation continued before Djentuh stabbed Tagaloa once in the neck with scissors. Tagaloa died within moments.

This raises three issues:

The futility of the death

The situation was entirely preventable. These are young men seeking to prove themselves to their peers by showing bravery and demonstrating their prowess and composure in a fight. They were seeking confrontation, with one man arming themselves when they knew a physical confrontation was about to kick off.

We can minimise this kind of outcome by providing opportunity, role models, purpose and discipline to young men, and an outlet to prove themselves and achieve self-worth. Suppressing competitive behaviour in boys and denying them these opportunities is how you amplify toxic masculinity. Their energy has to be directed into productive and benign pursuits. If they aren’t provided a positive group of peers and role models, they will find their own who may be antisocial in nature.

Scissors are lethal weapons

Secondly, this demonstrates just how lethal any type of blade can be. The next time you hear about police shooting someone after they attempted to stab someone with scissors, go back and watch this video, and remember what just a pair of scissors can do.

Bans on specific types of blades are fruitless

Where I live, we have banned the following types of knives:

  • Flickknife
  • Ballistic knife
  • Sheath knife
  • Urban Skinner
  • Trench knife
  • Butterfly knife or “balisong”
  • Star knife
  • Zombie Knife

Any object made of strong material with a point can be used to stab, and any hard material with an edge can be used to cut.

Banning any type of blade only results in the use of blades which are not prohibited, especially kitchen knives. Kitchen knives are typically made of steel, have a long sharp blade and a point, with a full or partial tang, and ergonomic handle.

These attributes make kitchen knives more effective as weapons than many of the banned knives, which are mostly designed for their appearance.

Knife designs can increase reliability and practicality, but they are all lethal, including cheap scissors purchased from a late-night corner store.

Laws which prohibit the carrying of blades and other weapons in a public place have more merit and real effect on outcomes, depending on the area and cultural context.

Male violence and gendered violence

There is a popular belief in Australia that domestic violence, and violence generally, is getting worse. However:

If homicide is the yardstick by which the level of violence in society is measured, then the belief that violence is increasing in Australia cannot be substantiated.

https://www.aic.gov.au/publications/tandi/tandi359

Most discussion has centred around women as victims of homicide, however, men account for about 70% of homicide victims. Over the last 30 years, all homicide has been falling.

Women are certainly over-represented in intimate partner homicide, but these numbers are falling along with the overall count:

The likely cause of the drop is due to the following factors:

  1. Improved socio-economic conditions, including employment opportunities, better education, economic stability
  2. Public health initiatives to address mental health issues and substance abuse – we know that people with mental health drug abuse issues are over represented as homicide offenders
  3. Demographic changes, because we have an aging population who is less likely to commit crime
  4. Improved law enforcement and judicial response, with more effective strategies, crime solving, community policing and prevention measures assisted by technological advancements

Further pursuing these issues will ensure that homicide continues to fall; conversely, a decline in our standard of living, and public health services, could result in more violence in the long term.

Also missing from the conversation is the fact that men are victims of male violence at a higher rate. If we want to prevent the murder of women, we have to protect men also.

All these points and more are discussed in the above video.

Police officer stabbed to death moments after arriving on scene – Las Cruces PD

Body Cam Video
CCTV Video

A stark and horrifying example of two things:

  1. The danger posed by knives, even when we are armed with a gun – you CAN bring a knife to a gun fight and win if you’re close enough.
  2. Not all situations involving mental health issues can be de-escalated verbally. Police have often been criticised in the media for shooting within seconds of arriving at the scene – this incident demonstrates the kind of situation which can lead to that happening.

Patrol Officer Jonah Hernandez was stabbed to death while responding to a trespassing call at the 300 block of South Valley Drive in Las Cruces.

A witness to the stabbing shot the suspect while another witness called 911 for help.

Officer Hernandez was transported to MountainView Regional Medical Center where he died from a knife wound to his neck.

The subject had a lengthy criminal record and mental illness.

Officer Hernandez had served with the Las Cruces Police Department for two years. He was survived by his wife and two sons.

Man taken to ground in street fight, brutal armbar follows

According to the source of the video on Reddit, this fight started after the drunken older man had been arguing with a group for about 10 minutes and was given many chances to leave.

The man wearing the ADCC hoodie (Abu Dhabi Combat Club, a prestigious submission grappling tournament) kicked off his footwear shortly before the video starts. Then:

Strikes -> clinch -> takedown -> mount -> armbar -> head stomps from armbar -> mount -> elbows.

Bystanders offered to call an ambulance for the older man following the fight, however he refused and kept saying that a bunch of “homeless guys” had attacked him.

As I’ve explained in a previous post, the standing vs ground debate is a red herring. Sometimes going to the ground is the optimal strategy, sometimes it’s not. In all cases, grappling skills are necessary whether you want to stay standing or not.

Saying “never go to the ground in a street fight” is idiotic, and at best a misguided oversimplification.

In this instance, the man who performed the armbar was not jumped by a group, was not stabbed, there was no glass and AIDS needles and lava on the ground.

It also starkly illustrates the effectiveness of join locks. This is not a submission, he did not wait for his victim to tap. He just destroyed that arm.

None of this is to say that his behaviour was justified, that’s up for you to decide. Where I live, it would be considered excessive and serious charges would follow. Make sure you understand local laws before using force.
