It's not really that ideal to prohibit going on duty as you're released from jail. Other people (warrants) surrender to LEOs to go on-duty afterwards, some log-in at the jail and may want to go on duty after.
If possible, just like weapons, armour should also stay within the class.
Regardarding the other issue, I think a restriction should be added prohibiting you the use of bribe cmd after being released from jail, this cooldown could range from 3-5 minutes (Where friends should've already been released by then)
