If we had the confidence he did not commit the crime we would have said so.
I read this sentence somewhere, shouldn't it be:
If we had had the confidence he had not commited the crime we would have said so.
In the case of the first sentence, if I altered the "would have said" part like this:
If we had the confidence he did not commit the crime we would say so.
Would it be correct?
The first correction represents the third conditional while the second correction represents the second conditional.
