So I'm going to do this for Game. . . . who will of course defend anything Navy. .. . . probably with good reason.
Someone noticed some dudes with hats at the Boston Marathon Firecracker event. I don't know anything about it, but they said they had the Navy Seal hats and T-shirts on, and there were a bunch of them on the scene moments before the Boston Maraton Firecracker "explosion". There were about twenty, and they were all carrying some standard pack of something. . . . They were walking around looking at everyone, forming a cordon around the spot where the "blast" was about to happen. . . .
In my first few minutes of watching videos online, put out by a recruiter office for the SEALS, there was brag about the mission including anti-terrorism assignments. . . . so there is a unit or two that does training mock-ups of a terrorism "event". . . . .
