Maybe . No. No. Yes.
Anytime a group of armed men stop me there is a threat of force. And if it's the folks in the vid "in charge" at the bundys the threat is high
The chuckles continue.
There's video of Checkpoint Bundy, now? If so, I missed it. I don't know how else you would know that the men who stopped the suspected cattle-rustler were armed at all, much less armed in any way other than merely having holstered sidearms, like most of us carry sidearms on a regular basis. And it would be interesting if you were to claim that having a holstered sidearm is in itself a threat of force. If they had any visible or concealed guns at all.
To answer your questions, I don't know how many people were coming down the back roads.
Most of the evidence is in the nature of people being subject to private security, on private property. On private land, how many people are stopped is up to the property owner/manager, and completely at his discretion, what contracts are in place, etc.
On public roads, no one should be stopped by force, or the threat of force, by any vigilante group.
OK?
