I don't think this clarifies the "spur of the moment" much but here it is in context:
REDDEN: Okay. Alright, so, ok, so, Saturday, what time did you go get that thing then?
WESTERFIELD: Um, lets see. I got up, Im guessing about 10 after 7.
REDDEN: Saturday morning?
WESTERFIELD: Saturday morning.
REDDEN: Okay.
WESTERFIELD: Went downstairs and opened the front door and turned off the front light, looked around. And got dressed, took a shower, got dressed. Then I left to get the motor home.
REDDEN: Okay, so was this spur of the moment or something you had planned?
WESTERFIELD: No, it was spur of the moment. Because I had a, you know, I had made a commitment to Gary to be at the bar on Friday night. And I knew that I had nothing really planned for today. So it was going to be Saturday, Sunday, and Monday.
It seems the media and the police used these statements as HYPE to get the public excited about their bringing home the BIG FISH.
They committed tons of YOUR money, and LE's time (more your money) to going after DW.
Once committed, there is no backing out.
Most people do not understand, even if the police find during the investigation that you are totally innocent, they have no obligation to testify/provide this info in court. IF they arrested and charged you, YOU Have to defend yourself, and if you can't, TOO BAD.
It was him responding to REDDEN stating 'SPUR OF THE MOMENT'.
IN court this would be called LEADING THE WITNESS.
DW then clarifies why he would agree to SPUR OF THE MOMENT.
So, my point all along has been that those that say DW LIED TO POLICE are trying to take what he said OUT OF CONTEXT, and I believe I am right.
He broke up with his girlfriend and decided to go camping to get away. He told his son he would be gone. He asked at least one friend to join him. He was unable to find anyone to go camping on Fri, so he made plans to hang out with Gary Fri night. Sat morning he decided to go camping anyway (spur of the moment) since he didn't have anything planned for Mon (when he was being questioned).
