No logical or reasonable comment on this matter will do any good at all.
Bloomberg's stated position is, "I've already made up my mind, so don't try to confuse me with facts."
How can any set of laws and regulations that affect the law-abiding have any effect upon a criminal?
Martinez was in illegal possession of a gun. He was already a criminal, by definition, because he hadn't taken out the required peddler's license. Possessing the gun was merely another criminal act. Further, he probably was in illegal possession the gun in order to illegally sell it to somebody else.
How can making more or stronger laws against gun possession have any effect on people like Martinez?
Bloomberg can't answer that one, so he merely avoids the issue and makes more anti-gun edicts. To the fools who vote for him, it appears that he's "doing something" about the problem.
But then, laws don't mean a whole lot to Bloomberg anyway. He's serving his third term as Mayor in a city where, until very recently, the law limited the Mayor to two terms. How come? Because Bloomberg changed the law to suit himself.
