A question for some of the more knowledgeable members here,

Whats causing the spike(real or perceived) in violence/crime in American cities recently.

Chicago seems to be getting the major media attention but places across the country from LA, to Milwaukee to Washington DC have seen the same effect.

Offhand I figured it was the booming heroin heroin trade and to a lesser extent gentrification driving this.

I know liberals like to blame guns but this seems to be more of a symptom then an actual cause.

Or it is somthing else entirely/or a mix of all of the above.

I'd def like to hear more!

Thank you in advance!
