Was it a tow truck or one of those "suck-up" trucks?

More likely they were going to repossess a vehicle - or were 'shopping' for one ...

They could have been looking for a vehicle to tow that had a pentagon parking pass.

Get the right vehicle with the right pass and then go to work.

Sure they could be legit. That's the point of good cover for action, it has to 'stand up' as legit.

The "we're just crooks" is also a ready made "fall back cover" if the primary does not stand up to scrutiny.

Yeah, maybe trying to steal a vehicle with a pentagon parking pass, load it up with explosives, pass through the gate then gun it towards the lobby...

I guess these two are about to Gitmo than they bargained for.
