Over 50% of Border Patrol officers are Hispanic; 20% of all ICE employees are Hispanic, with much higher percentage (e.g. 40%) in subsets such as field agents in Southern California.
Since it's perfectly well established at this point that one can be part of a given identity class while still supporting or actively enforcing behavior that's discriminatory towards the same identity class (not to mention inhumane in other ways), this is pretty much a red herring.
