Not a liberal person here. More centrist/libertarian etc etc, but from my perspective, here in Jersey those news reports are hyped for all they're worth.
The incidents DO happen, but in being virtually over-reported as they are, they almost create a confirmation bias which feeds on itself.
Then, not only do people get worked up, but then you have idiots who copycat for the notoriety.
Compare the amount of "knock-out" game reports vs muggings, fights, and so on, in every city on every day....
The 'knock-out" game stuff tends to sell more news but is an absolute miniscule thing in comparison to the other things that can befall a person.
So, yeah, it does happen no arguments there, but you really have to put it into a bigger perspective.
What I mean, is not to say that your GF's work area is all of the sudden perfectly safe, it very well may not be, but it may be unsafe due to a simple increase in crime in general...? Otherwise it may be that all the hype itself HAS actually caused a bunch of idiots with nothing better to do to jump on the bandwagon.
