It's a private facility operating under contract with the government. The illegals must have complained because they had to wait more than 5 minutes to see a doctor or could not get the pain pills they were after without paying for them. Also the food might not have been served on time or the napkins were paper instead of linen. And because this is a private facility they may not have had all the government forms ready for a driver's license, welfare, SSI, a Social Security card, EBT and voter registration forms. Also the illegals are complaining when they file a Federal Income Tax Return that their $6,000 Earned Income Credit is not immediately credited to their new Bank of America checking account. This holds up the process when they amend their return which gives them three more years with no proof of residency or citizenship required, which amounts to a total of $24,000. Sometimes they have to wait weeks for the deposit and this can contribute to unrest as well. You can imagine with all this abuse that they have every right to riot.
