I came across this odd box last Friday night in the Crystal City Metro Station, parked under the escalator and chained to the rail. It had a sticker on it that said that it came from the “Agon Force Protection” something or other. Hmmm. The bell on the top looks like a collector of some kind to trap particles in the air. My suspicion is that this is some kind of chemical or biological weapons detector, sampling the air for threats. Crystal City is virtually the Pentagon annex, where the overflow of offices go, just a couple stops from the Pentagon.
One wonders if the Crotch Bombers failed Christmas surprise has prompted a quiet security escalation beyond the arlines.
