Ok, so give him $20 million, with such a rationale. CT taxpayers didn't wrongly imprison him. The City of Hartford, prosecutor and jury did. CT does not have counties. I see no reason this should come out of general state revenues. Also, DNA techniques were lousy back then and are much improved now, so is it fair to say they bungled it so badly?
Because he was prosecuted by the PEOPLE OF CT!
In other words, the General State resources were used to convict him on behalf of the citizens of the State.
