I don't know what kinds of contingency planning may have taken place, but ultimately this event seems to have been ended and cleaned up pretty quickly compared to some other demonstrations we've seen recently.

This is worrying in its own terms. Policemen are adult, and shouldn't believe in fairy tales.

Being able to use deductive reasoning, understand basic principles of science (like the difference between cheratine and DNA), double-check the facts, and find the truth between the lies is THE work of the police.

Somebody unable to see a hole for years in theories that most 5 Yo curious children could dismantle in a hour is unfit for this kind of work. They simply shouldn't be policemen. Period. Will end distroying the lifes of innocent people.

There is not enough information to come to either conclusion, but I would like to think the DC police leadership didn't/doesn't plumb those depths of incompetence. The public (and congress) deserves answers on what happened and why.

Unless something more sinister emerges the simplest explanation is probably the best - there some cops who are far-right sympathisers and there are incompetently managed and organized Police forces. Both of those things are already demonstrably true and explain how the response quite well without introducing a grand conspiracy.

However, it is no secret that the FBI has long-reported (2006!) on white-supremecist infiltration of police forces[1] - this is not crazy talk. If someone joined the police as a rookie in 2006 to enforce their personal agenda, how far up the leadership hierarchy would they be now?
