Dead Friend of Boston Bomber Unarmed When Killed

So now it turns out--as we suspected all along--that the friend of Tamerlan the Boston Bomber was unarmed when shot and killed by an FBI agent recently in that infamous incident.  You'll recall that he was in the act of confessing to that triple-murder drug hit (with Tamerlan's help) in Waltham when he suddenly leaped up and, supposedly, attack one of the interrogators and simply had to be shot and killed.  Now it looks like he had not weapon and simply turned over a table and lunged.  Three armed agents apparently couldn't handle it.  I supposed this will only fan the conspiracy nut theories.
