At least FOUR clearly-marked police cars were visible.
Yet in that context: 151 firearms, 12 of which were long guns. The weapons recovered include: knives, brass knuckles, batons, tomahawks, weighted weapons, a hatchet, stun guns, bats, clubs, a machete, a pipe, an ax, pepper spray, and a chain. Many of these were hastily hidden and some were found using metal detectors as they were buried beneath the grass in the dirt were brought in preparation for a rumble among criminal tough-guys, then hastily hidden. LONG GUNS -- bikers with long guns. Who knew!
It is a ridiculous scenario. Bad-ass bikers are dumb-ass bikers, but they ain't that dumb, even in packs.
Confiscate 200 bikes motorcycles and search them all and thats about what I would expect to find. In Kansas none of it is illegal.
It's hard enough to fire a pistol from a bike, much less a long gun.
OTOH, I do know some folks who ride with a rifle mounted in a fork scabbard. There's a real nice looking WWII Harley in the area rigged up like that. I think he mounts a Garand to keep it in period.
