It sounds like the police and ice are getting a full list of guests and the type of id from motels. They are also looking for criminals with outstanding warrants. Sounds legit to me. Many countries have hotels turn over a guest list to the police. Sounds like they are now using some computerized system.
I agree. In the Kansas City area, law enforcement has offered up ‘anti-sex trafficking’ classes to hotel staff. I wouldn’t at all be surprised if sharing guest lists is an off-shoot of this.
