I agree,Olivant. Even if Michael would have killed Five Angels himself,he should still have taken the Fifth. The only thing I can figure is that in Mike's mind, he would attain some of the "respectability" that he so desperately wanted if he answered the Commitee's questions. Also, if he did co-operate and was not indicted,it would be a great PR victory ,and would keep the Government off his back for a while.

I always thought that one of the plot points that stretched things a little was Mike's ability to locate Vincenzo,get word to him in Sicily,and put him on a plane, all in the span of time that the Committee was in recess.
