I don't know. I'd like to think there would be more caution about jumping to a conclusion about any situation that is unusual but I'm sure the police get pressured for a result in a lot of cases, especially high profile. Forensics should be better 32 years on. I think there will be some learning from it, but as time passes who knows.
Forgiving - a lot of people would be bitter. I too don't know if I could be forgiving and have remained so composed in public - the frustration would have leaked out. I recall a radio interview some years back with an American woman who visited prisons working with offenders. What made it remarkable was what happened to her & how she forgave. To get an idea of the horror of the crime perpetrated against her & the level of her forgiveness, a backpacker tortured & killed her boyfriend, raped her repeatedly in all ways possible then slit her throat & left her to die on the side of the road. The american winter apparently kept her alive long enough to be found and "saved". He was caught & she watched him die in the chair. The comments that stayed with me was along the lines of... that after he'd died she didn't feel any release. She was still hating him. And it was then that she realised that unless she could forgive him she'd be full of hate for the rest of her life. And after that she decided that she wanted to work with offenders to try to help them.
Like that woman, the Chamberlains have shown a strength of spirit in a situation that would crush many people. Perhaps a bitter-sweet victory.
And the cost - financial and their marriage. Wonder how the kids are?
