You live in a society where cities are divided into zones, and humans are mixed in with people with powers (fire, strength, ice, telekinesis, electricity, and the most rare, healers). To use your powers openly, you need a warrant. Criminal organizations hire abnormals to do their jobs for them, and being caught using powers is referred to as a “Code 8”. To help the police officers, the city invested in “guardians”, which were robotic police officers.
