What is the name of the TV show advertised before the movie super 8?

Ok so recently i went to the movie super 8, before the movie started
(and before the previews started) they played some commercials for TV
shows. One of them showed a policewomen putting on body armor in a
locker room all tough and dramatic like. She was a fairly middle aged
woman.

I cant for the life of me remember the name of this show, and i really
need to figure it out because it had a really good bass line in the
background that i want to reverse engineer,

And id rather not pay 12$s to go watch a 20 second commercial =)

Thanks alot for any help!
