User blog comment:KibolLP 97/Mo van Barr's hat/@comment-1491017-20100901215220

Did you kill him as you shot his head off? If you did then you need to do it without killing him. Also, were to signed into your PSN account when you did it? Because I previously knocked peoples hats off while not signed in, but today while I was signed in and shot someones hat off it notified me I had got an item. Anyway these are the only reasons I can think of, good luck trying to get the hat.
