>> and tempers did flare while msnbc's cameras were in the yard. >> well, we had two northern mexicans jump on another northern mexican. it all stemmed over a disrespect issue. yesterday they beat him up over here in front of the yard shack. the guy that beat him up was the victim's age. this guy i know is in his 60s. apparently the northern mexicans felt he wasn't -- business wasn't handled properly, so therefore today they sent over guys about a third his age. the guys that beat him up today are probably early 20s, late teens. what you saw here today was actually a battery. they were stomping his head. you can see he's pretty messed up. lately the northern mexicans have been acting up more so than any race on this yard, beating up their own over respect
