Do you make an active shooter plan when in public spaces? [View all]

I just watched a video that seems to be pretty informative and thorough, but the problem is, if I have to plan exit routes and hiding places every time I'm in a public place, I'm not going to want to leave the house. I don't want to be a fearful, paranoid person, but at the same time, I'm in a state where you don't even have to have a license to carry anymore. The floodgates are open.

What do you think? Is this premature or should we all have an active shooter plan right now? Do you agree with this guy's advice? I don't want to live in a country where I need an active shooter plan.
