You can certainly cite individual examples. I'm sure there are a number of them. That doesn't negate albaby's point of presumption of innocence. And if you are innocent, then it's not right for you to be incarcerated for any time. Which is why they invented "bail". I don't know the particulars of any given case, plus any state laws that may be applicable. The judge(s) may have been following established procedure, or they may have been careless. Dunno.

That is the price we pay for a system where you are presumed innocent until proven guilty. Sometimes bad people go free (both before and after trial). We still end up with a shocking number of innocent people in jail, as later demonstrated when new evidence is found, or new techniques are invented (e.g. DNA freed a lot of people), etc.
