In a bid to investigate the reports, El Paso-based ABC-7 News contacted a number of federal agencies linked to border security and was told “the report is unverified, and it is unlikely that Isis is in Anapra or Juarez, Mexico”.
So no one knows for sure? But you're sure?
Yeah, I'm going to go with a member of Congress, Fox and the Independent over Judicial Watch which calls itself "a conservative foundation, fights for accountability and integrity in law, politics and government. Because no one is above the law!".
No one knows for sure that ISIS hasn't set up on Pluto. That doesn't mean they have. ISIS has its hands full in the Middle East. Most likely anything they get done here will be of the lone wolf radicalized US citizen variety not spending a fortune getting guys from the Middle East to Mexico to the US.
