Unless he was imprisoned in no particular place, at no particular time, then dates and locations are meaningful.
As you said earlier, this is a bio. Biographies have dates and places in them.
No, if you want to prove him a liar, then you need to find your information and prove it to us, asking me if I can name which base he was held and tortured at, and me not knowing, is not the kind of evidence you will need to prove Minister Cruz, a liar.
Which is your twisted obsession.
What can drive you to be so obsessed with trying to convince people that the Cruz s are lying?
