Quite a few bloody shootings take place throughout the film.
A teenager is shot in the chest by a cop, and he's seen hanging from a platform by his legs on a railing.
A character is assassinated.
A few characters are gunned down during a cottage raid.
The most violent scene occurs near the end, where a group of hitmen dressed in white - each with an automatic weapon - assassinates a room full of aging mobsters (their leader then casually shoots their dead or injured bodies with a pistol afterwards to ensure death), and then get into a shootout with police in an underground parking lot.
A mobster in the aforementioned scene is machine-gunned through a window while attempting to run for cover, and his body (clearly a dummy) falls from a high-rise building and we see him hit the pavement from a short distance.
An extended car chase between a cop and a biker tears through the streets, although no one is hurt except one man at the end of the chase, who is rammed through a storefront window by a speeding car.
