Seriously?
Yes.
From the articles,
"Last month, the team was involved in the arrest of Dzhokhar Tsarnaev, a suspect in the Boston Marathon bombings. And in February, it rescued a 5-year-old boy held hostage for six days in an underground bunker in Alabama."
First off, it was the same "team", they were training, and yes, they do protect others. Or did you think the Alabama rescue was staged or a gummint plot to cover up illegal aliens from Uranus?
