You’re sitting in a nice street side café in the location of your choice with the companion of your choise when you hear gunshots from a few tables over.
A scruffy man in scruffy clothes, looks like they and he came from the local shelter, is emptying a small frame revolver into the chest of another patron. After putting 4 or 5 rounds into the victim the gunman then tries to shoot himself in the head, but gets a click rather then another bang. He then sets the gun down on the table and starts to walk away. The diner companion of the man who was just shot is screaming historically and holding her dieing husband.
Prior to the shooting the couple had been talking loudly about their recent vacation or something, and at no point does the gunman say anything.
What do you do?
