Crime In Osaka

I have never seen the crime. But I live in Osaka. Osaka often happens some crimes. I watch the news, I hear bad news that it happen in Osaka. A lot of people live in there. So I think the crime often happens. Especially, It happens that the con-man call elder people, and he says,"Your son has big accident now, you have to sent much money for my bank! The con-man tell a story of lie. And he try to get money from elder people. Why their target is elder people? Because it is easy for the con-man to cheat elder people. And elder people believe that he talks story of lie. In the past, many people was cheated by the con-man. Now the number of damages are decreasing. Because some TV programs or commercials are often calling for attention. I hope the crime doesn't happen forever...
