Why did the ICE shooting happen? I think we need to look at the fact that this is a pervasive LE problem.

I think that over the years since the Vietnam era, various politicians, pundits and law enforcement officers have pushed a narrative that many criminals are "getting away with it" because they get released on "technicalities". Which often meant the officers grabbed the first black man they could find charged him with the crime, only to be released when someone with at least an average IQ stepped into the situation.
Because of this narrative, some law enforcement officers have taken it upon themselves to be judge, jury, and executioner because they don't trust the "system" to provide "justice".
If we are going to have re-education camps, we should start with law enforcement and then progress to the military. Because we have entered the era that was predicted in Star Trek TOS, where much of our population WORSHIPS the Constitution but have no idea what it means.
