you know... i'm not a fan of the cops either... but you know, you've got to be polite and nice to them, or they're gonna get not so polite with you. they are after all, humans just like everyone else. if some little shit starts mouthing off to me, i generally get in a not as nice mood as i was previously. same probably goes for the cops. just an idea.
and lol... if you really think that cops in other parts of the world are going to be NICER, (especially in a south american country) you are WRONG.
