Steve,

I could be mistaken on the jail time, but I vaguely remember David talking somewhere about jail. Could have just been an arrest and release, or I could be remembering wrong.

And I think Dean is correct. Harlow's blog is here and it seems to imply that he went out there to shoot a scene, but didn't... perhaps because Sean and Grant were working with police, and had no intention of doing the scene, but needed to get Harlow out there to get the confession.

If you've just knocked somebody off, it doesn't seem like hanging out with the guy that was the subject of the lawsuits and all would be the brightest thing... or, for that matter, making various jokes and obtuse references to the killing, as Harlow has done in his blog... but then again, Harlow doesn't seem like the brightest bulb in the box. (And does he really have a twin brother?)
