Can any say First Amendment lawsuit to force the government to get it's pesky, grubby little fingers out of it? Ahhh, yes. Where's the American Civil Liberties Union when you need 'em. A dollar says they wouldn't touch this.
Funny. You propose to help save druggies from themselves, you practically get city council members or deputy whomevers tripping over themselves for the photo ops near such signs. But the moment you propose to help all citizens save themselves from criminals, you get jumped on from behind by those same sneering city council pukes. (Or, whatever other city admin type cringed and disapproved of such life-saving measures.)
