 Person1:      It ’ s the same in my city . We also have a lot of drug addicts . A lot of the crime is committed by drug addicts who need money for drugs .  
 Person2:  That happens in many places . In my city , there is a very good drug rehabilitation programme . The police and courts are also tough on people who commit crimes , but I don ’ t know if that ’ s the reason for  
 Person1:      Some people believe that a tough approach is better . Other prefer a more lenient approach .  
 Person2:  I think that the best way to reduce crime is to spread wealth more evenly . If most people have similar amounts of money , they will not think of stealing from others .  
 Person1:      That ’ s possible , but I ’ m not sure it would really happen like that .
