Crime and general safety aren't valid factors for deciding where to live? Interesting, why not?

Living in the US makes sense for me now but if I were to have kids do I want to subject them to the active shooter drills that go along with the excessive murder rates?

We shrug our shoulders at the shootings in our neighbourhoods but there is an impact on quality of life.

Not really, one day coming back from work somebody got shot on the next car in the bart train i was on :)
