Assembly speaker to examine gun-possession law after GZ bust – Now she’s got Albany’s attention.  The Tennessee tourist arrested for bringing her home-state-registered handgun to the 9/11 Memorial has picked up some powerful allies in the capital — who plan to reassess the state’s stringent gun-possession laws.  Assembly Speaker Sheldon Silver (D-Manhattan), the state’s second-most powerful Democrat, said yesterday that he will have “a committee hold a hearing on this question, to see how exactly the law is being enforced and to look at the possibility that there should be changes in the law.’’  The changes could include tweaking the law to allow leniency for people with guns registered in other states who mistakenly bring their weapons to New York.
