I love trek because of the stories and examples it can give us about being more moral human beings...if you can get past the ridiculous plot problems to watch it long enough. So you are sitting on a Starfleet committee and you are a high ranking officer, at least captain. You have tons of experience under your belt either commanding ships, or leading men and women in various facets. Assembled for this committee you sit and listen to doctor lewis zimmerman give you his sales pitch about an autonomous hologram capable of instantly appearing and doing complex functions like ...treating aortic ruptures and brain hemmorages and designing borg nano probes to kill species 8472 (*cough*) This is all well and good ..and now to the point. You wonder why we don't have Emergency Security holograms instead. The ability to project 100 EMH's with limited tactical training (who btw cant be harmed unless you target the EMITTERS) would have ended dozens of episodes in mere seconds. Why not emergency engineer holograms? Hell we already know about how the EMH mark 1's were scrubbing plasma conduits.
