CHINA, 05/12 - Eight people were killed and 20 others were injured in a knife attack at a kindergarten in northern China. The attack began at 8 a.m. when a 48-year-old man simply walked into the private school.
At least 17 people have been killed and dozens injured in a series of alleged "copycat" attacks, which began in March. In each case, a middle-aged man acting alone attacked children with knives or tools.
Some speculate that these attacks are the result of lack of physical security measures, some feel they are the result of frustration with corrupt government officials, and others blame the lack of treatment for people suffering from mental illnesses.
