Ok, I thought the DA`s office wanted LS, an experienced homicide detective on the case. The R`s did talk to LS privately, and he went with the IDI theory. There is reason to believe he was symphatetic towards the R`s (but was that after he interviewed them- that they did not fit the picture that the media and police had portrayed). LS tactic was to become friendly with people who he suspected I believe, and at least he got the R`s to talk to him.
The stun gun theory, I don`t find it ridiculous to think about that possibility and find out if the marks could be from a stun gun. It seems many say it can`t, I`m not sure if it is impossible.
If the intruder wrote the RN after killing JB, he came to the kitchen and therefore the flaslight would be there, or if he just came up from the basement and left the house from the 1st floor, for example. About the suitcase moved, is it said somewhere that the suitcase was not initially under the window? It was moved, but from where? Edit. From the BP:"Fleet also noticed a blue suitcase was sitting underneath the window."
If you put Lou Smit on youtube, you`ll get this video where he illustrates entering through the window:
Edit. Sorry, you meant leaving via the window- well, he didn`t illustrate that, just said the intruder would find a safe way out.

The problem for me is who to trust? There seems to be conflicting and misleading info depending on the source. I`m really not sure, why I should think that Steve Thomas and the inexperienced BPD are more reliable than Lou Smit, John Douglas or the DA`s office. The outside experts I`m willing to believe.
