Replying to What's up with Denver and all these shooting sprees?

I'm not talking the "there's been 6000000 mass shootings" hysteria that the media puts out and lumps in gang banger triple homicides as a "mass shooting". I'm talking about legit psychos just going on a rampage because fuck it. Just reading about this shooting in Lakewood. Says the dude went to at least 3 different places. Obviously and thankfully he was very inaccurate but still, why does the Denver metro area attract a seemingly above average amount of psychos?
