It is kind of “unusual”, as you say, for him to be claiming that he thinks the guy was firing “an AR” - this from inside the house where nobody can actually see just what the guy had for a weapon. Just like the gal who allegedly shot up a school, allegedly got shot twenty times or some such number yet there weren’t bullet holes or blood stains visible on her body. Or like the strange behavior the supposed “EMT” folks at the St. George Floyd arrest incident exhibited. Maybe I’m being “too hypersensitive”, as you say, but it’s the little things that kind of “catch” in one’s mind, flagging that there’s something amiss in the narrative being fed to us.
