Forget the UFO angle for a moment. Looks like U.S. Customs and Border Protection (CBP) has a problem. Potentially “catastrophic,” actually, in its own words. But since De Void is just an obscure little UFO blog and the mainstream media doesn’t cover this stuff anyway, the feds will probably luck out and nobody else will notice.

Late Friday afternoon, De Void received an explanation for the agency’s refusal to release a very specific piece of footage one of its surveillance planes acquired over Aguadilla, Puerto Rico on the evening of April 25, 2013. In defending its decision to reject De Void’s FOIA appeal, the feds said releasing the video would compromise law enforcement investigations. Specifically, CBP cited Title 5 U.S.C. 552 (b)(7)(E). Here’s the accompanying explanation:

“Releasing this video would identify the techniques practiced by the agency during the clandestine aerial tracking of the plane. Most notably, it shows the specific vantage point from which CBP prefers to conduct its clandestine surveillance in relation to the target plane. Bad actors can identify specifically from what altitude, directional positioning, airspeed, and distance CBP hopes to surveil while avoiding the detection from its targets. The on-screen metadata compounds the issue. The bands of text at the top and bottom of the screen alleviates any guesswork on their behalf, specifically providing such exact information as the CBP aircraft’s airspeed, altitude, and the GPS coordinates of both the aircraft and the surveillance target.
