“If you knew anything at all about rules of engagement, the SS is not going to preemptively kill someone who is a potential threat. Legally, they must wait until the gunman opens fire.”
No. Just no. No rules of engagement requires you to take the first bullet before returning fire.
I am willing to admit I may be wrong about the SS rules of engagement (they are classified). But I don’t agree it’s a SS conspiracy to let Trump be killed.
