Don't worry, it's not loaded.
Terry Kath, of Chicago [the band] — being a gun enthusiast — took a 9mm semi-automatic pistol and began cleaning it. When Don Johnson yelled from the kitchen for Terry to be careful, Kath removed the magazine to prove that the gun was not loaded and pointed it into the air and pulled the trigger. However — in his inebriated state — he forgot that a semi-automatic gun has a built-in safety feature that prevents the discharge of a chambered round, if the magazine is removed. Upon reinserting the magazine, Kath put the gun to his temple and pulled the trigger, infamously saying,
"Don't worry, it's not loaded", in another attempt to prove that everything was safe. Unfortunately, with the magazine reinserted, the chambered round discharged and killed him.
