If I remember correctly, the FBI approached Randy Weaver to get him to be an informer on the Aryan Nation who had a camp in the area, when he refused, all his problems began.
I think it was the Aryan Nation, if not it was some other White Supremacy Group in Northern Idaho.
It’s probably the same MO the FBI used to get informants in the Gretchen Whitmer kidnapping plot and on 1/6.
They also pestered him to saw off a shotgun many times. He refused and they just kept it up. Eventually he agreed and that's how ATF got the warrant for the raid.
