The other thing I like to mention about Freeh is that (a) he caught the Unabomber by basically setting a trap and then laying back quietly and letting him give himself enough "rope" to "hang himself" with, to expose his identity, and (b) in the Penn State investigation, Freeh actually found a "smoking gun" email about Sandusky from 2004 that had been missed by prosecutors the first time around, so the man is very thorough and patient.
