fishermen don t cross into mexico on that lake any more. we did know there were attack. we didn t know where exactly. reporter: you had no worries whatsoever when you took those jet skis out? no idea. as tragic as this is what i think i m hearing from you is what the hartleys did was incredibly stupid. incredibly. reporter: fishing guide and resort owner speedy colette says business on the lake has taken a beating since the hartleys made what he called a stupid trip to see a sunken church. he is sick of the media attention and insists that the fish and the fisherman are completely safe as long as they follow the unwritten rules. this is not a jet ski lake. never a jet ski seen. here they come they show up on jet skis that they don t see then try it approach them and stop them, because it s a war over there.
