The concept of “innocent until proven guilty” only applies during a criminal trial, not to being detained, arrested, or held before trial.
The obligation is on the prosecution to prove guilt, not for the defense to prove they are not guilty.
The right to a “speedy trial” is frequently waived by the defense attorneys, as failing to do is frequently seen as it might “create a worse situation with the prosecutor or judge”.
Overall the court system is designed to wear you down.
