My little Coppers-Arresting is Magic

The Mane Six as part of the Equestrian Bureau of Investigation.

How do they cope without guns? They have special Cop-Powers:

Sergeant Sparkle: Magic Powers, Book Assault
Agent Rarity: Magic Powers, Scissors, Needles and similar sharp objects, sharp jems
Corporal Applejack: Bucks, Applemunition
Corporal Dash: Supersonic Speed Collisions, lethal amounts of Swag
Inspector Pinkie: Cake Assault, ability to chase and catch anything, no matter how fast, manipulation through talk-torture, Pinkie-Sense
Officer Fluttershy: Cuteness, "The Stare"

(I simply threw them random ranks, so if they don't make any sense, I'm sorry ^u^)
