This guy sells these 'Andre The Giant' stencils so that the customer can squirt his trademark on whatever public surface he pleases.In N.Y. Giuliani cracked down on assholes like this and guess what? Crime in general went way down. Everybody's quality of life went up. I guess gutting him and roasting his innards on a grill in front of his eyes is a little strict. Break his fingers and then make him clean up his mess with a toothbrush and some acetone. That'll work.
Broken window theory. It works.
Sure Giuliani cracked down on graffiti, as one of many changes he instituted. And you’re right, crime in NYC has gone way down, although certainly some of that is attributable to the stock market bull run which priced so many out of the city. While cracking down on graffiti likely had some measurable impact, it’s not quite the cause:effect that you suggest it to be. He also got rid of strip clubs, drug addicts, loiterers, panhandlers, trash, prostitutes, and panhandlers. The city is better off now, as I know very well.
I take it you seriously would like his hand broken for this; that strikes me as authoritarian. I’m OK with remunerating the aggrieved party and serving some jail time, but this is probably an irreconcilable difference between the two of us.
