Police shoot someone dead. There should, at the very least, be a reliable public inquiry into each one of these incidents. We could treat it as an air accident or a murder inquiry, either would work; but instead, there is nothing. Over the years, the anger about being exposed to the risk of being shot dead without consequences boils over, and suddenly there is fighting in the streets and on Twitter. The way to "reverse the trend" is for justice to be seen to be done within the system, so people don't go outside the system. After all, there's no way to end calls for people to be fired without infringing free speech.

Is calling the police on somebody making a death threat? That's how SWATting came to be a problem, after all.
