10 years ago I watched a gang of feral youts in DC strip a beverage truck clean of product in a couple minutes.
Cops showed up after the fact and had a lot of sirens and flashing lights but didn’t do anything other than direct traffic.
Certain cultures enforce laws.
Liberal cities do not believe in laws.
Antifa knows and counts on the police arriving later..
Loud and slow.
Old school police tactic when you want them to know you’re coming. Don’t want to chase or arrest anyone. And give them enough time to get away.
