Read up on Ludlow and Kent State if you think that ( as you stated) if LE did this they will have a lot to answer for. If LE did something they should have not it will be years before any one is held to account, if then, and if that day comes it will be some low level schlub or schlubs who get a wrist slap. The king decides who can chastise him, how, and for what.
In the age of information availability LE is pretty much vindicated by an overwhelming margin. You can cherry pick examples but it doesn’t wash. I.E. Hands Up!
