It's more of a practical concern. Our diplomats and their details operate in places like Turkey every day and we want those governments to grant us lots of leeway when dealing with the local population. That being said, this is a spectacular display of diplomatic idiocy.
This comment is pretty fascist. The notion that it's OK to run around assaulting peaceful protesters because that gives you the scope to similarly ignore human rights elsewhere, and the phrasing "deal with" ... really don't sit well with me. A lot of what is wrong with the world rests on this kind of thinking.
I never said it was ok to treat people like that, or that I agree with that line of thinking at all. Describing something fascist doesn't make me fascist. Just that I suspect that is the calculation that goes on when a person decides to overlook this kind thing (which would normally be dealt with as a criminal action). Also tried to point out that there are countless stories of American diplomats and security teams behaving badly.
