I think the capability of carrying armament is irrelevant as long as it isn't actually carrying weapons. Anything can be retrofitted, and even without modifications any aircraft is a weapon in and of itself.
From CBP's standpoint, it makes sense. What other unmanned aircraft could carry the same sensor package, while also being incapable of being armed? There's the Global Hawk, which costs about 10x more than a Reaper.
There's a reason that a civilian agency like NASA owns so many fighter jets (F-15/16s). R&D is expensive and there's no need to reinvent the wheel. (Also worth noting-- NASA also owns some Predator drones)
