State Police superintendent not sure when ammunition background checks will be ready – The head of the State Police said Wednesday he has no idea when ammunition background checks, a key component of the state’s SAFE Act, will begin across the state.  State Police Superintendent Joseph D’Amico said his agency is still trying to find the right technology that will allow gun shop owners to swiftly complete the background checks, but that, so far, the solutions have been elusive.  “It’s not ready today,” D’Amico told lawmakers during a hearing on Gov. Andrew M. Cuomo’s 2014 proposed budget.
