Crossfire: Well put, actually. I'm aware that no city will ever be crime-free because crime-fighting either on the side of law enforcement or citizens is basically just treating the symptoms of a disease and not the actual causes.
I'm not against helping people, that would be too contradictory. I take pleasure in helping others to the best of my ability and these sort of actions should be held in high regard wherever they are found.
I'm just saying that if a crime-fighter who's specifically trying to physically stop a crime, such as a mugging or rape/braking and entering etc, is walking around on patrol with nothing to go on except a few dots on a crime map, an immense amount of their time will be spent just wandering around. Eventually they are bound to bump into something suspicious but the odds will be stacked against them. I'm sure there are methods which could, idk, raise the likelihood of finding the aforementioned physical crime.
I've heard of some advanced algorithms some law enforcement use to try to accurately predict areas where crime is very likely to happen. Insider info on possible criminals and the things they tend to target could help. There's also the action of baiting but personally I've always felt it's just too, dishonest.
A detective like approach to finding crime without the red tape that can slow down law enforcement actions could possibly be more effective at stopping criminals than semi-random patrols. Thanatos claims to have had a direct hand in closing down meth labs and other things of that nature, so I suppose things like this are already allegedly taking place.
