This is the moment a quick-thinking female Russian tourist took down a phone-snatcher in Argentina. Video posted by journalist Gonzalo Benitez shows the incident on November 9 when two thieves snuck up on the 33-year-old woman while she was on a bike waiting at a junction in the capital Buenos Aires. As they grab her device, she manages to wrestle one of them off the bike and hold him until Good Samaritans rush to her aid and help restrain him until the police arrive. Officers were also able to trace the offender who fled on the bike and discovered 10 cell phones at the property where he was arrested.
Anarchy would shun them from social systems until they made appropriate reperations. They might be jailed, they might be exiled, they might just be cut off from all but basic food/services/etc.
There are law enforcement answers in anarchist societies that aren’t “have cops.”
