Yup, it went crazy.
Frankly, it might have only been a matter of degree, but just about every city went crazy when you had the combination of the start of the crack epidemic and a large cohort turning into their 20s with a declining urban economy. Every place had spikes in violent crime and murder rates and many had a rise in gangs. Guess what? That cohort aged, the folks who were going to shoot or be shot were shot or jailed, and surprise, crime rates went down. Didn't matter if it was stop and frisk Giuliani, Barry / Kelly outreach, Menino and the religious leaders building one city and doing anti-gun stuff. With the safety came the gentrification. It is almost as if the Mayors didn't really matter except on the margins (of course, then there is B'more . . .).
The spread of drugs and the coming of the GWOT led to a public tolerant of liberty restrictions and a court system more than happy to accept theories allowing it.
