Protecting ICE on raids. Sure sounds like interfering w civilian affairs to me. “The troops are authorized to detain people who pose a threat to federal personnel or property, but only until police can arrest them. Military officials are not allowed to carry out arrests themselves.”
By law a detention has to be based on reasonable articulable suspicion that a specific crime has been committed. Guardsmen/Marines have little or no training in this aspect of law enforcement. They do not have qualified immunity like law enforcement officers. This will be a disaster.
