9/11 perpetrators & use of 'Enhanced Interrogation Techniques' on them.
As of writing this post, the perpetrators of 9/11 are in US custody, but haven't being charged with anything i.e. not bought in front of Court to be officially charged for the crimes they committed.
The reason for this - Use of "Enhanced Interrogation Techniques" aka Torture on the perpetrators.
Now you may say, the crimes the perpetrators did were so heinous that they shouldn't deserve any say about how the they were treated after they were arrested, but removing of human rights is not the way it should have happened.
Bush Admin & subsequent administrations muddied the waters for prosecuting the perpetrators by using the "Enhanced Interrogation Techniques" on them.
Use of such techniques was just a way to express anger on those perpetrators with no insight of the future i.e. thinking about today's revenge rather than future prosecution.
The families of victims will never get justice until the perpetrators die due to natural causes & not because they were given the Death Penalty for committing the world's deadliest terror attack.
The perpetrators now remain in a lingo. Can't be prosecuted due to evidence against them was obtained by use of Torture ; Can't be released as no government official wants to be the one who lets the perpetrators be free
But the only people who suffer for this are the families of victims who will never see the perpetrators bought to justice.
