If only America were actually obsessed with credentials on this one...

But before playing into your hand further: It doesn't seem odd that most people are not mentally/physically capable of dealing properly with an active shooter/combat situation and therefor don't feel that they would/should be the person to deal with it. Gonna make the bold assumption that most people's job descriptions don't involve annual firearm training, and they would therefor feel more comfortable with police dealing with these sort of situations. Which is the point other sane humans are trying to make before you deride the conversation for douchery.
