The rule of law, by its very nature, serves the cause of justice. In doing so, it is often overturned, but only in order to ensure that justice is delivered and offenders punished. Protection from the state therefore is a principle that is relinquished by those who commit crimes; it is the protection of the state from such people that thereafter becomes paramount. The double jeopardy rule enshrines in law that the key factor in any trial is the quality of police work up to that point, rather than the actual guilt of the defendant. If abolished, vindictive policemen will not affect the integrity of the justice system, the case will still be judged by the quality of the evidence whilst the defendant will have recourse to protest their innocence. The potential for innocent people to go through the stress of further trials is a price worth paying to ensure the guilty do not walk free.
