"Law enforcement found Volz in his driveway and arrested him without incident, according to the complaint."

That's a complete lie. 

They were waiting in his drive-way, in a Humvee while a four-door Jeep Wrangler followed him up the Old Sterling Highway and both vehichles proceeded to ram his Escort as he pulled into his driveway, but sure, believe everything the FBI tells you ADN.

Oh and those flash bangs and AR-15's were non-incidental too....

I fully believe that it was an attempt to trigger him to fight so they'd have an excuse to shoot him.
