I like this idea!
Regular cops could use the anti-magic equipment (like surpressing handcuffs) and Elite Forces (like American SWAT) could use surpressing magic (spells like Slow, Threaten, Blind or Silence) along with the anti-magic equipment.

I'd like to see them in FFXV, because its world is very similar to ours.
People use cars there, their clothes are modern and so on...
