Once an illegal *steps onto the physical property* they are then on Mexican soil. That is their *return* to Mexico.

That's a good one I hadn't considered. It does have the proper stench.

Yeah, the “proper stench” is right.
Think about it.
If the police can’t go into an embassy to arrest someone because it is foreign soil, then anything can happen.
Remember that wikilinks guy?
He fled to an embassy in England because he was facing rape changes back home.
It’s been years and I think he’s still in that embassy.

I know of no law that states that only one building or location can be a legal embassy.
