DW lied to police.. It was not a spur of the moment.
Sorry, Since you did say you didn't think anyone caught it, let me inform you. Someone did, and brought it up. Someone brought up the obvious, that DW had CHANGED his plans and what he was discussing with police at the TIME of the CONVERSATION was about events that were SPUR OF THE MOMENT.
So, the original poster that brought it up was making an attempt to take a comment OUT OF CONTEXT to try and prove DW lied, and you just did the same thing.
