What country are you from? I believe your statement may only be true in the UK.
UK beeing influenced from the continent, and their own experience. You know from London Metropolitan Police those Bobby Whistles?
Maybe initially those just had been budget cuts, not handing out guns but just a whistle instead. Think Noisy Cricket weapon from Men in Black, just without any punch.
The statistics in the end round are speaking a clear language. There is no way back for the Unites States into a more peacefull statistical bottomline. The weapons are floating around out there. UK made that differenting experience and might wanna think twice.
