It's interesting that those on the outside i.e. Dominick Dunne, Shephard Smith and all of many of us here on FR are highly critical and someone like Boylan who has been privy to some of the inner details in the case i.e. actually been in the home and actually spent time with the only witness, has nothing but high praise for the witness and the SLCPD/FBI handling of the case.
What else would you expect Boylan to say..Do you think she'd say they're incompetent, messed up the case, hiding something, etc., don't you think Boylan is also interested and has questions herself? Do you think Boylan would say something negative, I doubt it.
I think you're reading something into Boylan's statement she didn't say. From her perspective as a sketch artist the SLCPD/FBI did well by not bringing in the type sketch artist that uses catalogs of facial parts, etc. which can interfere with the witness's recall. However, this to me points to the fact they had seen the kidnapper on videotape so had no need for sketches.
I also think it's clearly obvious the reproach being heaped on the Smart family by those like Dominick Dunne and Shepard Smith who are not privy to the details of the case would be more properly focused on the SLCPD/FBI who failed the Smart family. The simple fact that an ex-con who worked for the family and was suspected of stealing from them only a year before, had a more than standard business relationship with the family where they had givin him a vehicle, was not immediately tailed when they had placed hundreds of personnel on the case and was allowed to do whatever he did with that Jeep on Jun 7-8 and ride off with whoever he rode off with from Moul's on Jun 8, is a failure they can't rectify even if they're not involved in an active coverup.
