Complete absence of situational awareness – woman attempts to stop party

This is simply a failure of situational awareness. Woman attempts to put a stop to a large number of young people having a party. Any attempt here is toothless without a display of force. This woman is physically incapable of handling a single person here, let alone 100 of them. She must have had a remarkably sheltered life up to this point.

Victims head stomped after knockout

Victims kicked/stomped repeatedly on the ground when already knocked out.

Falling on a hard surface is enough to kill. Being knocked out allows an assailant to continue harming their unconscious victim without interruption.
