One of them was very justified.

Pretti was a cluster like I said. I don't think he should have been shot, but it's going to be really hard to find anyone guilty.

They're hands on with an armed person who is resisting them, and he is shot in the chaos. I personally believe the first shot was by the officer who drew, but was unintentional and I don't think he realized it was his own gun.

The time from him being disarmed to the first shot was well under a second, wasn't it? Not enough time to send a memo to everyone about the current status of the armed opposition.
