More MCJ control for MCSD;
allow MCSD deputies (Sgt+) to grab other department members (or something similar) to help better regulate the jail. As it currently stands, deputies have little power when SBI just goes around discharging their firearms or abusing inmates in the MCJ. This is quite annoying as a jailing deputy, because you're forced to let SBI do whatever they want and you have to sit, watch, and deal with the aftermath (or wind up getting involved with it).
This would be helpful for the MCJ, because it would hopefully fix the amount of issues inside the jail, due to other departments causing problems. Although they are not the only issue, I believe this would be a big step into making the jail better and run smoother.
(Side note; some more signage possibly mentioning to search subjects before entering the jail, booking evidence, and where to put inmates could also be beneficial)
