Shouldn't the IG's involvment happen AFTER the DOJ/FBI finish up ther investigation and not before as has happened? By the sounds of it, Horowitz is very limited in who and what he can investigate. Heck, he even has to guess at some things. How can one do an investigation in order to recommend positive change when the person doing the recommending isn't even privy to all the pertinent info?  Or, is Horowitz going to do a more thorough investigation #2 ,after the fact, when he has more info available to him?
