We have been getting behind the scenes looks from the Massachusetts State Police all week long, and it continues with these photos of the command post in Watertown from Friday April 19, 2013.

As you can see in the photos, things were very tense - as you could imagine. The Mass. State Police posted the gallery on their Facebook page today, and over the weekend we got a look at the method used to see Tsarnaev in the boat where he was hiding.

In the photos you can see Boston Police commissioner Ed Davis, Boston Mayor Tom Menino, MEMA Director Kurt Schwartz, State Police Deputy Superintendent James Hanafin and Watertown Police Chief Edward Deveau among others.
