No, there was little or no change to the NYC gun laws under his tenure. And there was no possibility of loosening the draconian gun control laws, with the overwhelming majority of NYC voters in favor of keeping them. That was the situation Rudy was faced with, along with all the garbage from federal courts that handcuffs law enforcement in its efforts to identify, arrest, and convict criminals and keep them imprisoned for appropriate terms. Stuck with this backdrop, he did a heck of a good job in reducing crime in NYC. He ought to get some credit for that.
Yet Rudy called for more federal gun laws. That seems to be one of the points that you don't want to address.
He wasn't just a passive participant, he was an active campaigner for stricter gun controls. And he sued gun manufacturers, blaming them for NYC street crime. He went well above just the laws he inherited.
Do you support gun control laws, so long as crime happens to go down?
