What evidence?
The curiously and mystifyingly direct corellation between higher concentrations of crime and higher concentrations of people?
The spectre of gangs and drug dealers and thieves being not just registered and active voters because they're so big on civics, but that these outlaws are registered to a party as they were instructed to by their local officials of only one party?
That the cities with the highest crime rates strangely tend to be in Republican run Red States?
When crime rates are looked at in terms of per capita as opposed to being a natural consequence of being places not festooned with tumbleweed to cover up their lack of people, the numbers come up a tad different, even for that go-to bogeyman fave of Righties, Chicago. That's why Juno has less crime than Chicago yet the state of Alaska has the highest violent crime rate in the USA in ratio to population.
Here's an example of a place with 'less' crime:

I suck at math, so go ahead, feel free to correct me on any errors. I'm still waiting for that OP to do so.
