If this is true, then it's time to get some, boys. No mercy: none has been shown us. Just obliterate the bastard and all that assist him.
No, no, no! This is a law enforcement problem! Bin Laden is simply a nuisance. Read him his rights, handcuff him gently, and escort him to the back of the squad car, helping him bend his enormous head so his turban doesn't get bumped by the squad car roof. Then get him a good lawyer, and release him after bail. Overstated threats never hurt anyone.
