In Brooklyn, some high school bullies carry guns, and one just killed a man over an Oakland Raiders cap.

Our friends at Gothamist just relayed the story of 38-year-old Gerald Cummings, who was trying to retrieve the cap after a kid stole it from his 17-year-old son, Gerald Sealey.

Sealey had been playing basketball last weekend at a court at a Brooklyn elementary school when a group of young men came up to him and stole the cap — which has a snakeskin bill and is apparently worth hundreds of dollars.

Then...

Sealey was at the basketball court again on Wednesday night when he saw his hat on one of the muggers' heads. He called his father, who lived nearby on East 18th Street, and Cummings reportedly came to the court, confronted the bully, and seized the hat back. But the thief and his friends followed Cummings and his son as they walked away. One of them pulled out a gun and started firing, fatally striking Cummings.

According to sources speaking to the NY Daily News, "The humiliated crook followed Cummings and his son off the court, trying to take the cap back when one of his friends pulled a gun from his backpack and started blasting."

Cummings was hit in the back, the back of his head, and the right temple, and he did not survive. He also leaves behind an 11-year-old son.
