this is about all gun crime that goes on around us:

Bang Bang,
1 bullet, your head! ,

Bang Bang,
all i can picture is a sea of red,

Bang Bang,
gona make you pay for everything you said,

Bang Bang,
makes me wana pull this trigger even more,

Bang Bang,
there you are laying on the floor,

Bang Bang,
you bleed from the hole in your head!

Bang Bang,
1 bullet - your DEAD!
