trying to hide their presence. On the contrary, they're wearing uniforms. I don't find it odd that the city of Boston and/or the Boston Athletic Association would have hired them for extra security. But I think it's odd that the msm wouldn't have noted that, given what happened.
And related to these guys or not, I also find it odd that journalists aren't doing more to question the loudspeaker announcement in which someone told the spectators something to the effect of, to not be alarmed about the (unusual) law enforcement presence, as it was only a drill. Who made that announcement? And why?
When we try to pick out anything by itself, we find it hitched to everything else in the Universe.
