How can Music be a Weapon?

For my photography assignment i need to take a series of pictures of a
crime scene and for a few of my pictures i want to use the concept of
Music is a Weapon and how music can play on so many emotions and as a
result can effect people mentally and emotionally, but i do not know
how to translate that into a photo. Does anybody have any ideas on how
Music can be a weapon? THANKS!
