I may be against execution, but I know that here trying guilty people and passing the drag sentence is not easy, it is usually 4-6 years between the judgement and the execution. And during that time the convict can appeal as many times as they wish.
The only thing that I see wrong is that interrogators lie to the arrested criminals saying that if they confess to their crime they won't be executed, so they confess and are told to reenact the crime to make sure and then they do believing by doing so they will escape the execution judgement for confessing.
That is he one thing I see wrong, however regardless, death penalty is clear, and I can guarantee no innocent person ever gets the sword. Unlike in Iraq where executions are used as a political tool. Killing as many Sunnis as possible, and saudi truck drivers on their way to Turkey for the pleasure of the on-lookers. So if anything iraq is the one that lacks a justice system.
