Jeebus, I hate loud music in public spaces too...
Ya know, giving people who "feel threatened" the right to shoot other people under "Stand Your Ground" laws is a really dumb idea, unless you want people who are already carrying and (so) feel threatened by just about anything -- like changes to the social order, say -- and to keep randomly blowing away members of the populace as a matter of public policy.
What next? "He looked at me funny?"
It's like we gave every asshole in the world a license to kill.
