Gibbs,
I admit I did kill a man with a credit card but it was for a very good reason. I will not try to defend my actions as I feel they were just, but I will explain why it was done.
The man was of the most despicable sort I have ever met. He was crass, a liar and a cheat, and he was laundering money using my credit card he stole among other worse things. So yes I killed him with it. Not after a huge amount of struggle I admit but he was just despicable so I took the card he stole and sliced his neck during a struggle. He died a quick but not painless death and I only regret that it didn't take longer. This was in Israel when I was still with my brother and the Mossad so there is nothing the US government could do to me and the Israeli government doesn't even know he existed.
So yes Gibbs I was not bluffing when I said I once killed a man with a credit card and now you know the story.
