my question to everyone here is about the police who showed up later. From discussions over the years here in the LR, my understanding was that the tactic the cops would take normally would be to contain the situation, take up a position and wait. This appears to be what they did. However when I do searches for this, I'm seeing they supposedly changed after Columbine. I realize this is probably a city by city or county by county policy, but when they review the actions of the police who showed up, my guess is they acted within their SOP. Whether that needs to change is another question.
What say you?
