Yes it is confusing . If you have not been though it or have a lot of knowledge of how a capitol case is prosecuted . TV shows a very simplistic vies in part because it would take a whole show just get through all the legal maneuvering that goes on prior to a trail that would not draw many viewers it is boring . It also would take hours to show a real capitol trail . The producers would have to doa lot of research and thaT meantime and money . TV unfortuantly is nota good source for legal information among other things .
There are two parts to a trail in which death is sought One is the guilt phase it is similar to a non capitol trail but is much more involved and very costly . Then there is the "punishment" phase in which a jury decides what punishment the defendant will face . in some states it is a different jury in TX it is the same one that convicted the defendant .
It isvery stressful o fro the accused and their defense counsel . From Jury selection called Voir dire . Where prospective jurors are supposed to state a number of things if they know any of the parties involved on either side , Any if they are cops or government employees of any sort sort have a relative who is in law enforcement or a prosecutor and much more such as if they have been arrested or have a realtive in prison any thing that can if they can impose the DP in a capitol case . This is one of the problems usually those who can impose death are inclined to believe the state in the first place making a up hill battle for any facing a potential death sentence . It is one of the major complaints that is used against the DP and a legit one . There is usually a evidenciary phase in TX the prosecutor control what evidence is shown unlike oterstaes that have what is called reciprocal discovery mean they have to share
ALL evidence prior totrail and allowed the defense to investigate it . This is usually true even in a non capitol trail
Then witnesses are called and examined by both side (hopefully ) this is another major problem in forensic evidence where the examines will perjure themselves or manufacture evidence to fitr for al kinds of reason from pressure form the prosecution to a belief the person is guilty and they should lie becuase thee evidence is weak ,flawed or inconclusive and in some cases a out right malice
Other witnesses also testify often they are pressured by the prosectuion to comit perjury or want to believe the person is guilty and testify to things that are not true thease are also problems in non captiopl cases . O they are just mistaken that happens far too often .
In the punishment phase victims survivor can speak a there are less rules and less ability for the defense to object . The prosecutor can make up any thing they wish usually trying to turn the defendant into a monster . the defendants supporters can speak also . on occasion a victims family has asked for mercy only to be ignored .
It is very emotionally and physically draining for the accused and thier counsel as they are fighting the state that has vast resources and the almost no accountability if they are wrong or deliberately convict a person for some sort odv political gain .
It is stil more invloved and I am sure I missed a lot.

It gives a good idea about the problems I mentioned .
The Innocence Project works with more than DP cases .So it will give you a good idea about things overall and the major flaws in our justice system not h just the DP The DP take attention away from other worthy cases where some one is in prison wrongly or serving a sentence they should not be .
