I think it would only be fair that the people/protestors demanding police/soldiers display their IDs also did the same so that they can also be easily identifiable in case they were to commit a crime.
To keep it aviation related too, I don’t think flying military helicopters at low level at night over a downtown city over the top of a mass of people gets a pass mark in the risk/reward category.There doesn’t seem to be much thought put into the optics of what is happening in Washington D.C. The pictures of having troops all over the Lincoln Memorial have stuck with me. I’m not close enough to say whether it is justifiable or not but I would have thought if they had to be there like the helicopters be careful how it looks. The shot that stays with me is like something from an end of the world movie.
