This is further proof that Armed citizens are better at protecting the public than the Police. Citixens who take the time to arm themselves are more knowlege able and better trained and practice more often than the police.
Police officers may practice twice a year just before they have to qualify, and clean their weapons as often. Officers only go through stress training once when they are going through the police academy.
Armed Citizens practice on average of 8 time a year and take constant care of their weapons.
