Right about what, exactly? You do know this is a random person talking out of their ass on the internet about how they want the justice system to work, not reality.
Have no fear, there would be an investigation and a jury and conviction before Musk is behind bars (LOL JUST KIDDING, Musk is rich and will never face consequences)
What does this have to do with holding someone for a year before prosecution? I thought we were all assumed innocent until proven guilty, unless those cops really are bastards omgg!
Jail and prison are 2 different things. You are held in jail, and may be able to be let out on bond depending on the charges against you, while you wait to receive your due process. You are not held in a prison until you are sentenced by a judge, following a conviction by a jury.
If your due process is violated and you are imprisoned without conviction, guess who would probably be interested in taking your case? Probably the ACLU.
