not really, he killed someone. The police had a duty to look into it and be sure it was all as it appeared to be.
The correct decision has been reached and I hope the authorities continue to support him and his wife as I'd imagine he is in a right state after whats happened.
It is farcical though, CVD.
Why couldn't he be just be brought in for questioning rather than on suspicion of murder?
How would you feel if someone broke into your house and after a struggle you stabbed the person in self defence and the next thing you know you are arrested on suspicion of murder?
You said yourself 'the police had a duty to look into it.' Well, that's exactly what they should have done, looked into it.
Just bring the bloke in for questioning. Why on suspicion of murder? It also suddenly went very quickly from GBH to murder.
I would say 'farcical' describes it all just fine.
