You were walking in the streets of the mafia infested city you lived in. It was late at night and you just had an argument with your friend so you decided to go for a walk to clear your mind. However you would do quite the opposite. As you were walking, the sound of begging echoes through a nearby alley. You hear a gunshot and then it goes silent. You peek into the alley and see the most feared mafia leader... Bang Chan

What will you do?
