You are referring to when the released the pics? They didn't know shite about those dudes until the killed the cop.
If you don't think they gleaned info of the little heartthrob chechnan, I don't know what to tell you.
Should we have just killed that mastermind who looks like Rosie O'Donnal? Thee 911 guy I'm talking about. We saved lives by getting info off that dude.
These brothers were not lone wolfs. They were trained on bomb making IMO.
Now, once we got the info we need, I agree, end that fricks life. But yo can't not ask him questions first IMO.
