I think crime is a major problem because of various reasons. If crime stopped, many other problems will be solved. Guns won't be used as much, less drugs would be dealed, and there will be less hate in this world. Crime starts when people don't have a life. Since this person doesn't have alife, he or she will turn to drugs.
Drugs can influence the person to hate people for no reason and they are killed with guns.
Crime has killed many people in this world. You might even know a person who was killed.
