ok - on BC and the police - a few thoughts.
I am a woman, so I likely wouldn't be looked at as the prime suspect if my husband turned up missing - so I am not sure I can relate to what he was feeling. Just like men probably can't relate to someone at the hardware store treating me like a moron.
I'd initially do whatever the police wanted. Then - if they were starting to look at me with the hairy eyeball and I was picking up vibes they were starting to build a case and not find my husband - I'd back off being as cooperative. My guess is that they were not too subtle in their suspicions.
Weird aside - when I was about 20 - I got a call from the police about money being missing from a store I used to work at. they wanted me to come in and talk. They had already spoken to my CURRENT employer and asked about my trustworthiness. I called an attorney. I was TOTALLY innocent. My attorney (friend) advised me to cooperate. I went in a talked - however, as soon as I would not comply with everything they wanted (lie detector test, videotaped interview with store people) and told them I wanted to talk to my attorney before I committed to anything they started getting aggressive. (This was state police by the way). I eventually told them I would take a lie detector if it was administered BY the state police - not some rinky dink operator that the store hired. Once word got out that this was my statement - there were TONS of people who started talking that I did it and made anything I did support that theory - I used to go to clubs so I stole money for that, or I had a nice car, or WHATEVER. then, as the lie detector time came close for the store employees that had agreed to do it - they started calling ME for advice! Suddenly, protecting your rights was not such an obvious sign of guilt. Ultimately, the store installed hidden cameras (as the thefts continued long past my employment there! no one bothered to tell me that) and they caught the middle aged woman who supported her ailing mother, stealing from the store. No apologies, no nothing - just a whole group of people who thought I did it - ONLY because I refused to walk like a sheep to slaughter.
Lastly, I went through a bad divorce. And honestly - if my ex husband had turned up missing, it would have been difficult for me to look sad. I know that isn't nice, but when you are really unhappy with someone - and they are making your like hell - and threatening you with a long drawn out divorce and trying to bankrupt you, etc - you see it would be easier for them to just disappear. Now - I would not have taken any action for that to happen - BUT - I had thought that a single car accident would make my situation a lot better.
I KNOW that is not nice - but it was a really not nice situation.
So - once again - that stuff - FOR ME - does not factor into my thoughts of ones' guilt or innocence.
(Honestly, Brad cleaning, the absence of the "sticks", the reading of emails later in the evening of 7/11, etc influence my thoughts of his guilt.)
