The March 14 directive, signed by Attorney General Pam Bondi, uses an obscure 18th-century law — the Alien Enemies Act of 1798 — to give law enforcement nationwide the power to bypass basic constitutional protections.
According to the memo, agents can break into a home if getting a warrant is “impracticable,” and they don’t need a judge’s approval. Instead, immigration officers can sign their own administrative warrants. The bar for action is low — a “reasonable belief” that someone might be part of a Venezuelan gang is enough.
That’s all fair enough. I’ve seen it listed as a gotcha on some very pro-gun sites for the specific case of a thief who’s taken something, jewelery for example, and is now running away. You can’t take the offensive to get it back. (At least not with your gun. I expect trackling them to the ground would be fine?)
That gets much, much more state specific. I can tell you that a lot of stores with loss-prevention officers aren’t keen on having them tackle shoplifters, since that can result in massive losses from lawsuits.
