The use of Brennan’s name has me worried. That is NOT a detail that I would expect a leftist false-flag operation to include. Everything else about his smacks of a false-flag operation. If it was a right-winger, he is a very stupid individual, because there is no way on earth this would help the cause.
If it is a false flag, of course Brennan would send one to himself, he’s the ringleader.
I don’t know, Brennan is a darling of the left.
