So you're saying Colin was wrong when he said that the money had been put up by members of the family?
Not at all, we are trying to determine WHICH bail / which arrest.
He was questioned in the 11th (poss 12th) and released on Police Bail on the 13th... (after which he broke into WHF, then went on holiday to South of France).
When he returned, he was arrested and charged.
These days, a suspect facing a murder charge is VERY unlikely to be granted bail, and if so has to be done by a crown court judge. Back in 1985, I 'think' a Magistrate could do so. (the law changed to prevent magistrates doing so, but I can't recall the precise dates)
AND, because it's in a book that Colin said so and so, doesn't mean Colin DID say that. He could have said they were prepared to put up bail....
I don't know either way, we're just trying to piece together bits of information and rule out what cannot be true, and keep in what could be true (some stuff can be proven to be wrong sometimes)
