There are way too many cases like this. How much can you compensate someone who spent all these years in prison unjustly? In many cases the states have passed laws to limit the amount they pay to unjustly incarcerated people so they may end up with very little money. But why should the taxpayers foot the bill once again? The cop in this case is dead (others involved who aided and abetted or covered up for him may be alive though) but even if he was alive he would not be sent to prison or pay anything out of his pocket.
I hear you. The problem is when these people (prosecutors, law enforcement, etc.) do bad things, the government is held responsible. The government = taxpayers. I don't mind the use of my tax dollars to compensate someone like this lady.
