Why is Dick Cheney on TV and not in prison?

It is interesting to see Cheney running to get in front of the cameras and claim that "torture worked". It doesn't. And even if it did, torture is immoral, illegal and uncivilized - whether it works or not is irrelevant. Arguing about whether or not torture works is like arguing about whether you can get rich making kiddie porn or whether eating live babies cures cancer (or helps wins majority governments).
