According to the live newscast I just watched given by the Uvalde chief, nineteen officers were on site and didn't try to enter the classroom because they thought he was a barricaded subject with no kids still alive in the classroom. I was never in a classroom that didn't have windows in it where you could see outside. Nineteen cops in the corridor outside the classroom and nobody thought to go outside and look thru a window to see what was going on, or to try and take out the shooter thru one of the windows? Unbelievable...
