Safe police weapons
Many police officers from around the world carry firearms while at work. While this does provide protection to the officer, it can also be used against him if it was grabbed in a fight. My idea is that police firearms would have small finger print scanners that analize the prints of whoever is holding the weapon. If the person holding the weapon is not the officer the weapon was assinged to, the weapon would refuse to fire. The weapon would also let out a huge electrical charge (80,000 volts+) that would immobilise the suspect. Although the shock is high in volts, it would have an extreemly low ampage (0.0001 amps maybe) so that it doesn't actually do any damage to the suspect.

Reward: fewer shot police officers
