A Ku Klax Klan adviser and a convicted felon taught Eagle Scouts and Civil Air Patrol cadets how to strangle people, decapitate enemies with machetes and fire semi-automatic weapons at a paramilitary camp, it was reported yesterday.

The Houston Chronicle said 12 to 30 scouts and cadets were instructed in guerrilla warfare tactics by Joe Bogart, a Klan adviser, and by John Bryant, who has been convicted of illegally selling automatic weapons.

The cadets, aged 13 to 19, are members of the CAP unit at Ellington Air Force Base. The scouts belong to Explorers Post 2125, backed by the Marine Reserve Corps at Ellington Air Force Base. Explorers is a program for scouts of high-school age through 20.

Several parents have said their sons told them the two men had made racial slurs about blacks and had given frequent lectures on guerrilla warfare, the Chronicle said.

Bryant contended: "We're not teaching these boys how to snipe. They only shoot a few rounds, not proficiently by any means."

Bogart, a Klan member for two years, claimed that during his four years of service in the Marines he choked other Marines into unconsciousness in boot camp. But he said, "We didn't have the boys choke each other, we just showed them how to do it."
