There was an article here just yesterday saying that violent crime is continuing to drop in NYC, so evidently Bloomberg has not reversed the good work Rudy did on that.
This is a lot of blather. Increasing penalties on shooting cops and trafficking in illegal firearms is not the same thing as taking away lawful weapons, so in practice that's OK too.
The problem is the language and the attitude. Plus the fact that ever since Murdoch's oldest son quit the NY Post, it has been moving to the left. The Post is getting worse than the Daily News, which doesn't leave a single conservative voice in New York City, other than the small-circulation Sun.
Illegal firearms? What part of either "shall not be infringed" or "cannot be infringed" is unclear. There can be no such thing, under either NY's civil rights law, or the Second Amendment to the US constitution. There can criminals who misuse firearms, there can perhaps be persons who illegally own firearms (assuming the disability was part of their sentence) and their could be other sorts of illegal ownership (ie. receiving and/or possessing stolen firearms), but there cannot be "illegal firearms".
