Apparently the fake ID charge was dropped. Now it has never been illegal to use an alias in the US, nor to possess documents under that alias unless you are using them to commit fraud, which an AP does not. I've made and used fake ID in casinos, and the only purpose was to give security guards a reason to stop pursuing who I really am. Interesting, it might be nice to have an informed legal opinion as to what kind of fake ID you can have and how you can use it.
