Notice at at the 6:10 mark the Border Nazi reads the procedure for refusal to go to "secondary". He says that you must remain in place and they give themselves the right injure you and damage your property, he says nothing about being arrested. That's because they can't arrest you and they know it. Its simply just intimidation so that you voluntarily give up your rights at security theater. No probable cause to stop you and detention without suspicion of a crime, these checkpoints are unconstitutional.
