Police Hunt Serial Killer of Brooklyn Shopkeepers | NBC New York A serial killer is on the loose in New York City shooting unarmed shopkeepers point blank. It is a good thing that Bloomberg has prevented those shopkeepers from owning guns.. They may have killed that poor serial killer. I just wonder how come Bloomberg failed to prevent the cold-blooded murderer from getting a gun? I don't know about anyone else, but I think the tyrannical mayor Bloomberg and his mafia-runned NYPD need to be held accountable for these murders. Why should people be kept helpless, while criminals run the show? Perhaps, its time that New Yorkers themselves become more vigilant and tell Bloomberg, NYC gov't and the NYPD to shove it..
