I'm afraid I have to put my tinfoil on. The incident is starting to sound Waco-like.
Still no explanation of the bogus traffic stop at night. Why not arrest them in broad daylight, or as they were entering or exiting the meeting in John Day? Or while out buying groceries, which worked in the past? Or if they were really only after the one person LE killed, why didn't they wait for an opportunity to arrest him with fewer other people to deal with? Hwy 395 between Burns and John Day was an interesting choice for a traffic stop.
While I still think the group was pulling bonehead moves, this time I think LE did so, with lethal results. Possibly because of pressure from the Governor and others. They still would have had several months for other options to present themselves before the Refuge is scheduled to open back up to the public.
Also, it appears the group said it was a "hands up, don't shoot" incident, but Al Sharpton hasn't rode in yet demanding a White House investigation.
