There has been an alarming trend of artists being hit with items or assaulted during their concerts, and Adele addressed the situation at a recent show. 

A clip from her Las Vegas residency shows the singer holding a t-shirt gun while telling the crowd, "Have you noticed how people are like forgetting f***ing show etiquette at the moment, people just throwing sh*t on stage have you seen them? I f***ing dare you to throw something at me, and I'll f***ing kill you."

Adele then launched a t-shirt at the audience and stated, "Stop throwing things at the artist when you can shoot it to people. [Laughs] I've been seeing these people, these people lost it."
