CNN.com - Agent: Police did their best for man wearing bomb

I have been meaning to post on this story ever since I heard about it last night (I haven't watched TV all weekend long!!!).
That is the strangest thing I have ever heard and I can't imagine having anything like that happening to me.
Who would do anything like that? And believe they could get away with that?
I hope they solve this because it is somewhat irritating that, whoever did this, is still out there and could possibly do this to somebody else.
