Wild videos released Wednesday show the chaos that erupted when two gangs opened fire on each other on a busy Brooklyn street, killing a former aide to Gov. Andrew Cuomo in the crossfire.

NYPD Detective Raymond Wayne walked jurors in Brooklyn Supreme Court through the clips as part of the trial for four men who allegedly killed Carey Gabay in the shootout during the 2015 J’Ouvert celebration.

The footage, taken from nearby businesses and a police officer’s helmet-mounted camera, capture revelers running for their lives as the shots rang out, and are filled with shouting, whistles and flashing ambulance lights flashing.

One video shows alleged gang member Kenny Bazile climbing up a staircase with a gun in hand, while another shows his co-defendant, Keith Luncheon, with a gun in his right hand.

Bazile’s lawyer claims he was only shooting in self-defense, while Luncheon’s claims his client was forced into a false confession.
