Government can never keep a lid on anything. They don't need to. All they have to do is keep saying "Bah! Humbug!", or ignoring it, and the majority will sing along, primarily because they don't care one way or the other.
Meanwhile, a minority drives itself nuts trying to figure out how to make people recognize what they don't want to recognize............
It was classic law enforcement; let the idiot talk himself into jail. The authorities were nowhere to be seen or heard (just like the PG event) until Smeja provided the evidence that pinned him: the "steak". Dead meat. The authorities even let somebody else pay for the forensic examination (DNA analysis) that came up as bear.
Then they closed in. They simply interrogated him, let him lie, and then indicted him on felony perjury charges along with all the minor fish and feathers accusations that really don't mean squat. It was all an afterthought, because it was easy, and the entire effort was simply to seize his firearms and ban him from possessing them for the rest of his life. They don't care about dead sasquatches or dead bears. They wanted those guns.
They're going to get them, too.
