Now watch it over again... look at the Mexican guy in the white shirt and the black hat. Wow, he can really jump in a hurry when he needs to.
A couple months ago there was a similar incident in Spain, a bull jumped into the crowd and injured 40 people.
Evidently these bulls (on steroids?) need to be fenced in better. Time to add an extra foot or two to the height of the fences.
A similar incident happened in Edmonton at a rodeo recently. Skip forward to 2 minutes 20 seconds to see where the bull jumps into the crowd.
