Due Process

10 facts:
1.) In 1992, a man called Kevin Rojas was sentenced for life for a crime he did not commit.
2.) The lead/reasoning for his conviction was the orange color of his jacket, and false witnesses.
3.) Many shocked witnesses/referrals in court (i'm not sure the people who testify against the defendant) weren't able to supply valid forms of evidence against Rojas.
4.) In a death sentence, there is a 25 year jail-time wait until the actual execution.
5.) Only 5% of cases use DNA to help figure out who is guilty is a crime.
6.) Rojas spent 4 and a half years in jail before the court figured out the injustice of their wrong decision.
7.) Since there was no concrete or DNA evidence in the case for lawyers to work with, they had to use many more methods of crime solving to figure out the case; which is probably why it took so long to get Rojas free.
8.) Groups working on cases such as the "Last Resort", often spend around 10 to 15 years on these cases.
9.) Centurion Ministries have freed 44 innocent people from false convictions in the last 30 years.
10.) Police, in their reports and initial actions of a crime, have overall the first and most influential judgement on the starting part of the case.

Questions:
1.) How does such a serious mistake in a crime happen in such a sophisticated court?
2.) Did Rojas receive anything for the time wasted in his life? After all, he was completely innocent.
3.) There has to be something to be done to achieve justice equilibrium with Kevin Rojas, how do you pay back hard time in jail, especially 4 and a half years worth?
4.) He was convicted by false information offered by "witnesses", don't they deserve to receive a punishment?
5.) What are other serious cases of false convictions? Are there any where the actual convict was found and forced to serve the punishment?
