Jailing rights may also be more appropriate over ban rights for new/trial police staff, it also gives jailed players the opportunity to PM staff RCs to dispute their punishment (ever been jailed after a bush NPC has repeatedly set your chat to "you are such a ****... bush!"?).
Jailing can also be handled automatically should someone be caught hacking via script, as can a scripted IP ban, but not a normal ban.
