A week ago today, 11 people were tragically murdered at the Tree of Life synagogue in Pittsburgh — the latest mass shooting in the U.S.

On Friday night, a Pitt player — DB Damarri Mathis — celebrated a play by miming shooting a machine gun, drawing heavy criticism.

You can see the celebration, which immediately drew a flag from officials, in the video below:

Fans were naturally outraged, and took to Twitter to call out the player for his incredibly tone-deaf celebration:

There’s really never an appropriate time for a machine gun celebration, but especially considering the recent tragedy in Pittsburgh, Mathis’s actions are especially egregious.
