I usually reserve judgement for criminal cases, but I'm SO TIRED of stupidity. If a cop has a reasonable request (like turning down blaring music after already being warned), just do it. Even if you don't see the point of the request, is it really worth playing with fire if there is nothing legitimate to gain by doing so? Don't act like a ****. Don't try to laud your rights. Don't be a bro and try to show them up. I have interacted with a bunch of cops in the past, and as long as you are courteous and give them respect, they are do the same for you. When people start treating them like **** is when things escalate and you end up getting arrested for loud music.
