Death row is the place usually located in a certain high security area of a prison, that houses prisoners who are waiting for their execution. After a criminal is evicted and is found guilty of an offence the judge will then allow the jury to either decide life in prison which is around 30-35 years or give a death sentence, then it is up to the jury to debate and agree to whether the death sentence should be finalised and in most instances it is an unanimous decision which means everyone in the jury agree and vote the same way. If it is agreed that the death penalty is to occur then they will stay on death row during appeal and habeas corpus procedures.
The picture on the furthest left is hanging, and the one next to it is a piece of experiment used for beheading. These are methods of execution which were a population during the 17th and 18th century. The third picture is the electrical chair and fourth shows the bed the inmate is strapped into for the lethal injection.
