According to the new law passed in NY, a doctor or a NURSE can deem someone mentally unfit to possess firearms. They are also immune from civil liability in this capacity. I think that is too much unchecked authority for someone to have.
That is all ancillary to the bigger constitutional issue of limiting magazines to 10 rounds, arbitrarily classifying weapons with cosmetic features as "assault weapons" and banning weapons that are used for self defense and in common use throughout the country. When/If SHTF and governments cannot provide for their citizens, their laws will no longer apply and you will be left to fend for yourself and defend your families. If you are a NY resident (or CT for that matter) you will be fighting with two hands behind your back because of these policy decisions. This is "feel good" legislation that was jammed through with no public input and the whole thing should be tossed by the Supreme Court as being unconstitutional.
