The police in New York are testing a hi-tech scanner. They say (it) can detect concealed weapons. They say trials of the new device started a year ago are at an advanced stage. Barbara Plett in New York has more.
纽约警方正在测试一种高科技检测仪，据说可以测出隐藏的武器，警方称对这种新仪器的测试开始于一年前，目前已处于高级阶段。Barbara Plett 报道。
The device is a portable box that can detect concealed weapons from a distance of around 10m. New York's police commissioner Greg Kelley says it measures of form of natural energy emitted by people and objects known as terahertz. If something is obstructing the flow of that radiation like a gun, the scanner highlights the object and it appears as a shadowy image. This has been seen as a possible alternative to the NYPD's reliance on the policy of stop and frisk which has raised serious concerns about racial profiling. Critics say the vast majority of on-the-spot weapons checks target blacks and Latinos.
这种便携式盒子装的设备可以在10米开外侦查处隐藏的武器，纽约警察局长格雷格?凯利说，该仪器可测出人和物体散发的名为太赫兹波的自然能量。如果有某种物品挡住这种辐射的流动，比如一把枪，这种装备就可以重点指出这种物品，然后以阴影表现出来。有了这种设备，纽约警察局就可能不再依赖于拦人搜身，而这种做法已引起人们对种族定性的高度担忧。批评者称大多数现场武器搜查都针对黑人和拉美裔。
