“Citizen’s Arrest Felonies. A person can arrest someone that they reasonably suspect of committing a felony,...”
“Repeatedly entering the U.S. illegally now a felony”
So you should be able to arrest an illegal assuming they are trying to re-enter the US again and hold them until Border Patrol can arrest them and clears up their status. But no the government is again siding with the illegals after filing to fix the problem for 30 years.
The latest twist from the feds and the state governments is to claim that someone doing a citizen's arrest is "impersonating a police officer" and therefore guilty of that crime. No doubt they will use the testimony of the illegal aliens who will say "I thought he was a police officer" just after they say "I want asylum because I am in danger of my life in Honduras"
Wouldn't it be nice to have a government that wasn't corrupt?
