It seems obvious that the Uvalde School Board is in complete disarray, and is lookin for a solution to a problem that has already happened.
That the School District police dropped the ball on the day of the shooting has been established, and beat to a bloody pulp, but you now have on display, a group of school board members that don't know, and never did know, what they were doing.
I think what started this firing was, the school board hired a female police officer that had been an on scene Texas State Trooper and along with ALL OFFICERS on scene, are still under investigation.
They have requested that the Texas Dept of Public Safety provide Troopers for security while "security fences", security doors", and "security windows" are being built, and installed.
Which if they had already been built, and installed, likely the school district wouldn't be in the position they're now in.
Too little, too late. But then again, 99% of all schools in Texas, and the rest of the country, ARE STILL SOFT TARGETS, and are ignoring the signs of the times, and hoping it doesn't happen to them.
