"Disclosure - I provide computer software to law enforcement agencies. However, I believe that some of the speculation of law enforcement agencies ganging up on innocent citizens is overblown - primarily because there is little incentive for law enforcement agencies to work with each other. For example, while it is technically feasible for agencies to exchange information, the completion of an inter-agency agreement to share information is often a stumbling block. I know nothing of CrimeDex, but I would suspect that agency restrictions on sharing information would apply for stuff placed on CrimeDex in the same way that it would apply for stuff placed on U.S. or Canadian government-owned networks." - Ontario Emperor
