The cop didn’t rob him. He seized illegal profits. You don’t arrest for all offenses, sometime you write a ticket. You don’t want that to happen to you? Obey the law and don’t operate without the proper papers. Btw, don’t blame the cop, he was just doing what he was instructed to do. If you watch the vid, it says the cops were told to crack down on illegal street vendors, and they were told to seize the profits.
I have a feeling that if this guy had been white and spoke English, no one would make a big deal about him getting ticked and his profits seized.
