Again, I am a not someone with a law degree. This commentary/Analysis is purely amateur
In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence (source)
This basically is the amendment that gives you the right to have counsel (AKA A lawyer). You have the right not to waste in jail waiting for a trail to happen, and a right to view the evidence against you, and compile evidence in your defense.
I don’t think this amendment is much debated as much as people wonder about the limitations of the law as new technology and investigative techniques come into play.
You often hear on crime shows how they hate the fact that they can’t hold anyone longer than a law given amount of time without evidence. This protects individuals from being imprisoned for crimes they did not commit, or being held on no charge whatsoever. Sadly it still happens, as we have learned over the years from falsified evidence, mistrials and people who are found innocent decades later.
If you click on the source link, it has an essay there that goes over the history of the Sixth Amendment and why its different than other systems of justice. Its an interesting read.
