where have the most recent high-profile shootings been? Colleges (VT, NIU), malls (Omaha, SLC), churches (one in a parking lot, one inside), grade schools (Columbine, amish elementary school), etc. With the exception of malls which must be posted 30.06, all of these locations are restricted by Texas law. It would have been ILLEGAL to protect yourself
Very astute observation.
Common sense dictates that someone planning to carry out an active shooting incident would select a venue where his victims are required to be unarmed so he will be unopposed and thus successful in causing large numbers of casualties. This is, of course, what they do, and it works - except where they are met by an LEO or armed citizen, which happens all to rarely.
Common sense also dictates that folks who don't want this to happen should prevent incidents by not creating unarmed victim zones where killing people is easy. Making the bad guys worry about immediately effective countermeasures is the most effective way to minimize violence.
There are three reasonable inferences one could draw here:
1) Active shooters have a lot more common sense than a large number of lawmakers and the folks in charge of securing the places where people study, worship, and shop.
2) A large number of lawmakers and the folks in charge of these venues don't really want these incidents to stop, and thus continue to employ proven failed protection methods while making a show that they do so because they are really concerned about safety.
3) A large number of lawmakers and the folks in charge of these venues are afflicted by a form of group mental illness that compels them to keep doing the same things over and over while fervently expecting different results from event sequences that happen almost exactly the same way every time.
Take your pick.
