Back in 2003 Ranch Rescue was the first to set up citizen patrols in south Texas.
They didn't shoot anyone but pistol whipped an illegal and the Texas Rangers went after them. They never could convict them but Casey Nethercott was a felon in possession so he was sent back to prison.
Then the illegals went after them on a civil complaint. The ranch owner settled out of court for a $100 grand, and Nethercott lost his 40 acres located on the AZ-Mex border in the judgement.
S-S-STFU
Well there is always shoot,shovel and shut up. :-)
