Williams seemed to think he had it all figured out and that he knew how to outsmart police, but I watched the police interviews with him yesterday and I thought he was completely unfamiliar with police interviews.
Police said that they were executing search warrants on his home as they spoke, but I don't think that was entirely true. I doubt a matched tire tread was enough for a search warrant on the Colonel's house. Perhaps after matching the footprint, an application for a search warrant was being drawn up ... by whatever assistant chief crown prosecutor had the weekend rotation ... but that had to be drafted, and signed by a judge before the search could take place. I think Smyth told a number of lies to lead Williams to believe that he was caught ... clever police work, but at the same time ... if Williams really was aware of how police operate, he wouldn't have willingly given them so much information.
I wondered how things would have gone if he had lawyered up and refused to provide any information ... like boot prints, DNA and so on. I think it would have delayed the inevitable, made it more difficult for police, and put Williams in a position where he would have had to explain himself to his superior officers (ie: why wouldn't he provide DNA, et cetera). I think he knew right away that giving his DNA would lead to his arrest, but I think that at the same time he was hoping to pull rank, so to speak; hoping that police were only doing some routine collection of DNA and that it would be put on a shelf for months (like in the Bernardo investigation).
