AMARILLO, TXIn spite of the George Jones cover band and the Porterhouse steak dinner, the Lifeloc FC-10 Portable Breath Alcohol Tester was the hit of the Amarillo 12th Precinct Police Jamboree Monday night. "Hey, hey, hey, hey, it's my turngimme that or I'll shoot ya," said a besotted Sgt. Bill Dugan as he pawed at the breathalyzer in Officer Jack Ermi's mouth. "I just did five Cuervo shots, and I wanna see if I can get my blood number thingy up to .300." Attendees at the Jamboree said passing around the breath tester was nearly as fun as the impromptu pepper-spray fight at last fall's Coptoberfest.
