I don’t advocate searching cars without probable cause, but when I see these guys driving down the street with a beer can or blunt in one hand and the bass thumping out the windows, the beer can or marijuana give *obvious* probable cause. All I’m really saying is that more often than not, at least in my neighborhood, super-loud stero noise is a clue to other unlawful behavior — aside from that fact that the noise-blasting is illegal (ticketable) on its own.

As far as vendors with cell phones, why not? Vendors really should have cell phones for personal safety anyway (all the ones I know do), and I think most of the legit ones would report something like a fight or gun-threat without prompting. The main reason to make that a license requirement IMO is to make sure casual vendors feel like they’re part of the community instead of outlaws who exist on the fringe of society.
