Ah, the old "hot-blooded Latino" stereotype! Vincent J. McMahon, who ran the wrestling promotion now known as WWE before passing it on to his son Vincent K., famously chose the Philadelphia Arena over Madison Square Garden when it was time for Puerto Rican Pedro Morales to lose his title, fearing a riot by New Yorricans in attendance at MSG. Even with the change of venue, McMahon ordered the finish of the match to be deliberately unclear (both men's shoulders on the mat simultaneously) and the ring announcer not, under any circumstances, to announce the winner. Instead, he said "Let's hear it for a great champion, Pedro Morales." No belt was awarded in the ring, either. No riot ensued.
Of course, McMahon was spooked by an incident in Boston about a year earlier, when a Latino Morales fan rushed the ring with a knife and opened a gash in the leg of Morales' opponent before the match even started. That's the way stereotypes take hold.
