Were you, like, reading? Orbs are simply not something to be relied on. Any sane person will use his powerful orb only in case of emergency and pay hefty price for it. Possibly die. Weak orbs may not even be worth using. And yes, orbs are still a subject of research. So I guess police of their world values lives of their officers more than insignificant ability boost (cuz, well, there are other tools and equipment besides orbs and boring police uses them instead of suicide tickets).
