What's your point and why is that surprising? This is what they do. MLK wouldn't have much to do if there was no injustice to fight. He was fighting laws which by definition are meaningless without enforcement (FBI) and be was not trying to change things from within the system (because he can't really). But then he won and the country changes, democrats are no longer racist people and southerners (at least not any democrat majority) and along with that many laws changed so now you can expect the FBI of today to support and protect MLK. But if you find injustice in the laws of today, get noticed enough and they will be on you like a fat kid on cake. Excerpt now, they are more sophisticated and tech has made their job both harder and easier in scary ways. It is a function of law enforcement to especially enforce unjust laws and orders be because those are the ones that need the most enforcement.
