Ok, there has to be SOMEONE on here who worked for the Central Artery/Tunnel Project Public Safety Department. I recall before it opened taking my kids on the walk through. I saw a number of uniformed and armed cops wearing the CAT patches. I saw at least one marked cruiser with blue lights. In other words, I know for a fact that the BIG DIG had it's own cops, but now, no one knows squat about them. Where did they go? What did they do during the project? Where did they derive their authority? How big was the department at any given time? I don't ask because I'm a "Why did they exist and screw them" kind of guy, I just love to know this stuff and frankly would LOVE to get a shoulder patch!!!! Is there ANYONE here who worked for them and can give some information. You can either post here (that would be nice) or PM me. I just GOTTA know! I asked before but never got any info. Were they CIA and no one is allowed to talk about them? If that's the case, I do NOT want to know!
