Were the BATFE involved before or during this “action”?
Publicly, they showed up after the shooting to assist with the crime scene and the bullets recovered were sent to their labs. The bodies were sent out of house as well, to an organization in Dallas. From the name I can't tell if it is public or private.
That's the $64 thousand dollar question. Who is that undercover cop and what was he doing minutes before? Probably cause because they were wearing vests. We've heard that here before.
