Does reading a lot of Wikipedia give people a wrong idea how science works?

If that's not true, why it is that school shootings are far more common in California than in Texas (California being the state with the highest number of school shootings)? In Texas, teachers are usually armed. In California, teachers are almost never armed.

School teachers in Texas are not ‘usually armed’. There are 1200 school districts in Texas only a quarter of those districts have armed staff. And, since which schools have armed staff is kept secret, it’s extremely unlikely that this is a deterrent (the psycho who shot up the school in Uvalde last year had no way of knowing if staff were armed).

I think it is precisely that that's a deterrent. It's why concealed carry acts more as a deterrent than open carry: there is a chance your victim is armed without you knowing that.
