On Sunday, more than a thousand people joined the prayer walk to honor Deputy Goforth. According to the National Law Enforcement Officers Memorial Fund, 15 police officers were killed and ambushed since last year. That`s triple the number of ambush shootings in 2013.
周日，一千多人参加纪念戈福斯的祈祷行走。据国家执法人员纪念基金会表示，自去年起，有15名警察被杀或遭遇伏击。这是2013埋伏枪杀数量的三倍。
Many police units are now equipping officers with body cameras. They can cost department`s thousands of dollars, both for the cameras and the space to store their information. But supporters say their benefits are well worth the investment.
许多警察单位现已配备了人体相机。相机和信息储存空间的花费达到数千美元。但支持者表示它们的益处是值得投资的。
CNN LEGAL ANALYST: Proponents of body cameras argue that video recordings will provide a real time objective record of an encounter,allowing for review of incidents by police supervisors, the prosecution and courts.
美国有线电视新闻网法律分析人士：人体相机的支持者认为，在冲突中录像将提供一个实时客观的纪录，能够为警察主管、律师和法院提供事件回顾。
A 2005 International Association of Chiefs of Police report found that cameras helped law enforcement, improving officers` safety, often backing up the officer`s version of events, reducing department liability and conveying to the community a sense of transparency.
2005年一项国际警察局长协会报告发现，相机能帮助执法人员提高警员人身安全、证实警员事件说法、减少部门责任以及向社会传达透明感。
The effectiveness of body worn cameras is still being debated. However, in one experiment, after the wholesale adoption by the police department in Rialto, California, complaints against officers drop by nearly 90 percent. In a pilot project in Mesa, Arizona, 75 percent fewer use of force complaints were filed against officer who wore body cameras than against officers who did not.
这种穿在身上的相机的有效性仍在讨论中。然而，在加利福尼亚里阿尔托警察部门，大量使用相机后投诉警察事件下降了近百分之九十。在亚利桑那州梅萨的一个试验项目中发现，投诉警员的抱怨中，使用了人体相机的比没使用的低百分之七十五。
But there are those who oppose the use of body worn cameras. Privacy concerns are often raised. In fact, video from dashboard cameras in police cars, a more widely used technology, has long been exploited for entertainment purposes.
但也有反对使用身体相机的。主要涉及到隐私问题。事实上，广泛使用的警车仪表盘摄像技术一直以来是以娱乐为目的的。
But while body cameras may not be the sole solution, they may be a powerful tool used to protect officers wrongly accused and civilians who complain of excessive force during encounter.
尽管人体相机可能不是唯一的解决办法，但在冲突中能为被错误指控的警员、抱怨过度使用武力的平民提供一个强大的保护工具。
