This feature should be removed from the server or get improved because it doesn't seems to work right at all.
It is very annoying to get jailed even tho there isn't any cop around you.
A lot more reasons why it is annoying are:
Self defence - Getting wanted level cause you fight back but you die so you're the one who gets jailed literally for nothing.
Wars - Between in a war with a lot of players everyone dies, but only few can get jailed instead of everyone.
Bugs - Dying by any sort of bug (like collision) while having wanted level.
A lot more can be added.
