At any rate this is going to continue to happen in our country no matter how hard things are tried to prevent it. If it's not a school, a mall, a grocery store, a company, or people gathered for a concert ....these “shooters” are out there just waiting and planning for when they do their deed.
Unfortunately when it's kids in a school it's esepcially difficult.
Saw A guy who went into a store with bows and arrows and hit five people. Go figure.
The tragedy can be minimized if we did away with the shooting galleries known as "gun free zones." Texas law allows for teachers and staff to to be armed with specialized training. Over 110 school districts in Texas do this. Uvalde was not on that list.
If staff and teachers are armed it would be much more difficult, possibly to the point of dissausion.
Let them pick a ‘gun free’ zone to attack. I go armed to church.
One report was he shot his way in, wounded the armed school officer on the way in, then wounded two more police in a shootout, before the special team went in. That was Daily Mail.
