That's a pretty interesting statement. I mean, first of all, it's pretty well documented that cops are some of the least trained gun handlers around. Cops don't shoot their guns much, and when they do it's more often than not to disasterous effect[*]. But it does open up the possibility that you'd feel safe if the people around you who were carrying guns _were trained to some level of competence that you approve of_ ... you've only just presumed that this is the kind of training that cops get, but it's no secret: non-cops can learn such things as well.
I agree with you: education is an excellent idea.

[*] Cops are far more involved in shooting the wrong person than non-cops.
