alt Hacker News> Despite the word "warrant" being present, an “administrative warrant” does not allow law enforcement to enter private property.
Even an actual judicial arrest warrant doesn't (legally) allow them to enter private party on suspicion that the target might be there. Search is a separate thing from seizure, and you need a judicial search warrant to search a private residence or the non-public areas of a business for a person, no matter what authority you might have to arrest them should you find them.
That makes sense. But that raises a separate unrelated question; how do bailbondsmen seem to be able to take their targets in, are they violating the law or are criminals gullible or something else?
