Wow, that is a lot to process. The bald off duty officer in the suit took charge and neutralized the shooter. Several other uniformed officers hid under cover and may want to reconsider their current profession. I hope her son pulls thru, but while he was still breathing in the video, it didn't sound good based on the radio traffic.
Yup- that's the TABC guy.
Unfortunately, from other reports, the kid is now pretty much just a functioning brain stem. It's not indicated who hit him.
