That trespassing thing is total bullshit, unless the business has signs posted they can do shit. Cops also can’t break up a group like that unless the storeowner called the cops them selves. If cops want to dish out their bullshit I can to, but mine isn’t bullshit. Most of the time cops leave me and the group I’m with alone because they know I know my rights and wont hesitate to express them in a legal court manor!
