You guys do realise that the incidence of violent crime has been steadily dropping for the last 30 odd years don't you? OK.. I'll grant you there is a slight rise in assaults but if you look closely its closely correlated with being in the wrong kind of nightclub at 4am smashed off your face.
All figures publicly available -

At the same time reporting of violent crime has risen and the perceived incidence of violent crime has also risen.
So you are safer than ever but feel less safe than ever.
Stop watching the news. Put the guns away and just have a homebrew.
