The law, the blob and fruits and vegetables are all part of today`s commercial-free coverage.

法律，黑点，水果和蔬菜，在今天不含广告的商业新闻中都会包括。

We`re starting with a look at the impact that cameras are having in U.S. law enforcement. Civilians have them on their phones. Police are increasingly using body cameras.

首先来说美国警员佩戴摄像头工作的情况。我们通常是手机上有摄像头。警员使用身体摄像头的人数正在上升。

The footage that these cameras capture and the public`s access to it, is having a tremendous influence in the court of public opinion.

这些摄像头捕获的镜头和公共访问入口对法庭公共观点产生了很大影响。

For example, some of the massive protests in different U.S. cities that have followed the controversial deaths of suspects at the hands of police. And some other investigations that have cleared officers of wrongdoing when body cameras confirmed they followed the law in confrontations with suspects.

例如，一些对于在警察手上发生的死亡案件的争论引发了美国不同城市的大规模游行活动。当警员按照法律佩戴摄像头时，与犯罪嫌疑人发生冲突行为不当的嫌疑也会被洗清。

With multiple protests and investigations going on in different cities around the country, we`re taking a look today at how the use of police force is defined by the U.S. Supreme Court.

随着全国上下多地发生抗议事件我们将会对美国最高法院对警察暴力这一定义进行分析。
