The problem is, and I tell you this having worked in this field, interrogations no longer work like they used to. Our ability to operate under strict legal requirements, when the host country has a say in prosecution, cripples this effort. It leads to very little interrogations of value, and a revolving door of terrorists that spend little time in prison before being released to kill again.
Killing them loses potential information, but it was information we weren't going to get anyway. It also cuts down on repeat offenders delightfully. It's a much better way to operate against terrorists. In this day and age, I'd rather interrogate a man's cell phone and computer than the man itself.
In this case I agree and supposedly we lifted all kinds of hard drives, DVDs and flash drives from Bin Laden's lair
Bin Laden would have become a rallying point and liability if alive.
Far better we killed him and disposed of him at sea like some garbage. He is dead and gone.
We can interrogate all his computer files and other stuff we took at our own leisure
Plus Bin Laden was kicking back with his two wives. Bin Laden being holed up was not so active as before. Not so much valuable intel could have been extracted from him.
