If not for those meddeling patriots alerting a cop that there was a shooter on that roof and that cop alerting that sniper and that sniper blowing yearicks brains out Yearick would have been snuck out of there and Crooks would have been swatted within hours.
Think that over and put the puzzle pieces together.
I don't think Yearick was intended to get out of there. Maybe they told him he would, and he thought he would, but they knew it would be much easier to kill him.
But if that was Yearick, then where is Crooks?
Crooks right now is supposed to be dead... what happens when they set you up as an assassin and you are supposed to be dead?
You're not Crooks, and I'm not Crooks, that's two of us.
