Probably not often. In Michigan terms, imagine this all transpiring in Lapeer or Adrian or some place like that.
I know that the job is dangerous and I don't want to be too harsh on police, but the job is pretty attractive as well: it pays well, the benefits are fantastic. Even in states like Texas which are hostile to union membership, their ability to unionize is practically sacrosanct. Outside of maybe the fire department, they are the God's of civil service. They are valued far more than the guy who works for the Public Works department who keeps the water tap running or the the Parks Department employee who keeps the parks clean.
But that level of value that they provide comes with the expectation that when the rubber meets the road, that they will put their lives on the line to take care of problems as they arise. And this was just a global failure all around, and hearing all the fallout from the event and how public officials are responding here locally, it is (correctly) delivering a blow to all the "thin blue line" virtue signaling that abounds here... the contours of the debate over policing after the George Floyd protests still exist to an extent, but I do think that the "police are never wrong" subtext that the "thin blue line" flags and decals convey is being challenged.
