'with the firepower to kill every police that showed up'

This claim is dubious. Police officers in Austin wear Level 3A plates which can stop 5.56 which is likely the round that AR-15 is chambered in. Landing 5 headshots in quick succession without getting taken down is something you only see in movies.

Aren’t officers also trained to seek cover first?

I didn't want to go into that. I just wanted to point out that it is absurd to claim that this random civilian could gun down five police officers in the matter of half a second and not get taken down.
