On Wednesday, the The Big Lead posted footage of a fan brawl that took place in the parking lot of MetLife Stadium in New Jersey following last week’s preseason game between the New York Giants and the New England Patriots.

The video below, via YouTube user WeLikeToHike, shows several people wailing on rival fans, some of whom are on the ground or have their back turned.

A quick search of YouTube reveals that those two fights were not the only instances of violence during this preseason. And those were just the incidents that were filmed.

Of course, this is hardly a new phenomenon. Fans have been fighting in the stands and the parking lots of NFL stadiums for many years.

Teams have taken certain measures to try and curtail fan violence. At MetLife Stadium, where the Giants-Patriots melee occurred, alcohol sales are cut off at the beginning of the third quarter. And fans “exhibiting visible signs of impairment” are denied entry, according to MetLife Stadium policy.

But obviously, these measures aren’t enough. More needs to be done. People could get seriously hurt.
