It doesn't. If you confiscate an ID document you are supposed to turn it over to law enforcement. You don't just get to build up a collection of other peoples stuff.
In many states possession of a fake ID is a crime, in addition to laws that cover use or intent to defraud.
But what if law enforcement is manufacturing fake ids themselves?
That's one of the many ways Trump loyalist Matt Gaetz's best buddy pedo-pimp Joel Greenberg got in trouble, making fake ids using information from surrendered driver's licenses.
>The report claims that some customers came to Greenberg’s office to surrender their driver’s license -- for instance, when they were receiving a replacement or renewal -- with the understanding that their old ID would be shredded.
>Instead, federal prosecutors allege that Greenberg used the information from at least two IDs, one from Florida and one from Puerto Rico, to create a fake driver’s license that would have his picture on it along with the victims’ names, date of birth and other pertinent information.
>“Joel Micah Greenberg used the surrendered drivers licenses that he had taken to cause fake driver licenses to be produced that had his photograph but the personal information of the victims whose driver licenses he had taken,” prosecutors wrote.
