Its somewhat ironic that indeed the death penalty in the US has given a number of defendants a 2nd chance insofar as it forced closer examination of a said trial and any incompetance by the law enforcement agencies is generally brought to life. In many cases the police have been able to put someone in jail for the rest of their lives even though they are innocent and because they are not on death row - they dont get the attention that others get.
