They should be arrested and deported. Don't blame Texas. Blame Congress and the last 4 or 5 presidents.
I blame everyone, including those who think that illegal aliens just want a better life.
And yes they should have been arrested and deported, but the police protect them. I had an illegal steal some checks from a business account, write them as paychecks to himself, cash them. My bank caught it and they were returned. The DA went after ME for writing bad checks, and never went after the guy even though he had outstanding warrants.
The police are often complicit in this.
