No, Chris. A murderer is a person who has committed a murder. An accused murderer is a person who has been charged with murder. A convicted murderer is a person who has been tried and found guilty of murder. Not every murderer gets accused, much less convicted, and not every convicted murderer is actually a murderer (wrongful convictions do, unfortunately, happen). If any significant number of accused murderers are released due to delay, it is effectively certain that some of them will, in fact, be murderers.

However, you're quite right that people should not be locked up indefinitely just because they are accused of something. Note that the Jordan time limits apply to people who are on bail pending trial. It seems to me that the time limits should be much shorter for people who are being held in custody pending trial.
