Leonel Arias, 47, told police he was playing a practical joke by donning the Bin Laden mask, toting his pellet rifle and jumping out to scare drivers on a narrow street in his hometown, Carrizal de Alajuela, about 20 miles north of San Jose.
Arias had startled several drivers that way on Monday afternoon. But when he jumped out in front of taxi driver Juan Pablo Sandoval, the motorist reached for a gun and shot him twice in the stomach. He was hospitalized in stable condition.
"For me and I think for anybody else at a time like that one thinks the worst and so I fired my gun," Sandoval told Channel 7 television.
