“别在肮脏的快车道上送命。” 这是美国加州阿尔塔迪纳公路巡警站墙上贴的一条标语,告诉巡警们执勤时要小心谨慎。由于工作原因,我和加利福尼亚的交通管理部门的关系还不错。在我的一再要求下,警方同意我到基层部门和公路巡警一起工作几天。直到临出门穿上防弹衣的时候,我才认识到这项工作的危险性:生死攸关！ “Do not kill on a dirty fast lane.” This is a slogan on the wall of the Altadena Police Corps station in California, USA, telling the patrols to exercise caution. Due to my work, I have a good relationship with the traffic management department in California. On repeated requests, the police agreed that I should work for a few days with the grass-roots departments and highway patrolmen. I did not realize the dangers of this job until it was time to go out and wear body armor: life and death!
