有没有可能在中国持枪不合法，所以犯罪嫌疑人多为持刀伤人，选择目标更易偏向柔弱的女性和弱小的小孩子。。。更蛮横一点的凶手直接见人就砍不分男女。国外的持枪群伤杀人案一般都无差别攻击，犯罪嫌疑人有绝对的武力压制。
If there is a possibility that guns are unlawful in China, the suspects are more likely to hurt people with knives, and are more likely to target women and small children who are weak. More aggressive killers can cut men and women without distinction.
