All of those situations were attrocious, and I don't think anyone would disagree. Three actions in the last what? 8 years you site, out of the THOUSANDS UPON THOUSANDS of things the FBI does annually, and you assume this visit, triggered by terrorism against america is going to be the next Ruby Ridge or Waco? Yea, you're not paranoid with dillusions of self importance are you?
I'd say he's more than justified to be skeptical.
I would say if you are skeptical of statitical odds that are less than that of dying in the bathtub, that you are not justifiably skeptical, but unable to rationally understand statistical odds.
As for the FBI and their requirements, they can go pound sand. If they won't follow the US Constitution, we will elect someone to abolish them as an agency altogether
What unconstitutional action are you referring to? They asked if they could talk to the guy the guy said yes... there is no constitutional issue here... I got news for you, had they just wanted to be jerks, I guarantee these agents could have gotten a warrant and just showed up. This guy needlessly created a confrontational situation, he did not behave civilly and basically acted like a JERK in this instance.
Owning a .223 caliber rifle and a white van constitute probable cause that a person may have committed a crime? I don't think so.
