That guy was arrested because he was a felon and wasn't allowed to have a gun. He should go to jail for that absolutely.
That is detached from the issue at hand though. These people did nothing that the police don't also do based on the video. They weren't actually holding people at gunpoint, they just had guns which is totally legal. You don't even need a permit to open carry in new mexico.
What are people supposed to do? The government refuses to do its job so now people have to do it for them. We increasingly don't have a choice but to take matters into our own hands. The government takes your money and gives it to people who aren't even legally allowed to be here. Soon we won't even be able to pay for the programs we have like social security let alone pay for all of the poor people rushing into our country expecting handouts that are stolen from the rest of us.
