“Did they just sit there watching multiple felonies being committed...”
What multiple felonies do you think that they saw happening BEFORE the violent shootout?
After all, once they saw the violent shootout they did act to stop it, so you can’t possibly be complaining about that...
You should click the waco keyword and read up on the event. There was a brawl before shooting occurred. A brawl means multiple assault-and-battery charges. Why were the Waco Police at the scene before any crime was committed? What were they expecting to happen? Did they ignore the commission of multiple felonies in anticipation of making a more important arrest?
