Better policy is the answer, not bigger guns
If saturation policing was the key to dealing with violence, the combined muscle of the RUC, the British army and the UDR would have ended the Troubles in no time. It didn't. If building more jails was the answer, then the prison-heavy United States would have low crime rates. It doesn't.
