Detectives, their gun, and supercopping.

[BaneOfGiygas]

I should clarify that just because the detective is a separate entity from the security officers does not discount him from being part of the security team. I sometimes take over as pseudo-sec as a Captain or other head position, because while heads are not and never will be technical security officers and consequentially don't have the same sway, they still have the common goal of not letting everyone get murdered. It's sort of a similar case with the detective. This common purpose and goal of preventing murders means that, as simple consequence, they should be able to work together.

Should the detective have the same sway and overall level of authority? No.

But should the detective be able to cooperate with the security team instead of running around doing his own thing independently of them? Yes.
