> even though the charge of hiring a contract killer to assassinate his business competition may have been dropped
Just because the charge was dropped doesn't mean he's innocent of it. In fact, reading the chat logs makes his guilt pretty clear. Of course, because the whole operation was a scam, there's little he could have been convicted of. Yet just because the murder was never carried out doesn't mean he didn't intend to have someone assassinated. In my book, paying someone money to kill another person is definitely grounds for imprisonment.
That’s exactly what it means under the presumption of innocence.
Advocating for the continued imprisonment of someone for something they are legally considered innocent of, is quite literally vigilantism.
If you had a trial and they can't prove that, then yes it means you are innocent of this charge in the eyes of the law
