I think this whole thing about the 911 call and how the details were apparently not relayed to LE for the stop highlights a problem that gets swept under the rug: Dispatcher training. When a dispatcher doesn't take a call seriously (like when the social worker called to report Josh Powell taking his kids, after which he killed them and himself), or when they don't fully share details with officers which could very much change the outcome of a police interaction, there should be consequences there. There was a case in my hometown when I was young, where a person was getting beaten to death with baseball bats, multiple people called 911 to report it, and listening to the heinously indifferent attitudes of the 911 operators when those calls were released to the public, gahhhh, it's choking me up just thinking about it.
