美国警方上周五表示，芝加哥一男子在Facebook上直播自己的视频时被枪杀。
A Chicago man was shot dead while live-streaming a video of himself on Facebook, police said last Friday.
在芝加哥城西，28岁的安东尼奥·帕金斯头部和颈部中枪。这一视频在Facbook上仍然可以播放，目前已经被观看了大约70万次。
Antonio Perkins, 28, was shot in the head and neck on the city's west side. The video is still available on Facebook and has been watched nearly 700,000 times.
这是芝加哥在不到三个月的时间里第二次有人在Facebook的直播上被枪杀。今年3月份，一名身份不明的男子在直播中被枪击16次。两起案件的犯罪嫌疑人都未被抓获。
It is the second time in less than three months in Chicago that a shooting has been streamed live on Facebook. In March an unidentified man was shot 16 times while broadcasting live. No arrests have been made in either case.
Facebook的流媒体直播功能允许任何人在线实时直播。这项功能在2010年的时候就发布了，但是在近几个月才成为社交网络上的战略重点。
Facebook's live-streaming feature allows anyone to broadcast online in real time. It was launched in 2010 but has become more central to the social network's strategy in recent months.
这一视频显示，在枪声响起前，帕金斯曾和另一群人交谈过。在画面消失之前，直播用的手机滚到了鲜血淋漓的草丛中。
The video of Mr Perkins shows him and a group of people talking before gunshots are heard. The phone then appears to tumble through bloody grass before going black.
Facebook的一位女发言人声称，这份视频并没有违背公司的政策。她表示，如果一份视频赞扬或者美化了暴力的话，Facebook就会把它删掉。
A spokeswoman for Facebook said the video does not violate company policy. The social media site would remove a video if it celebrated or glorified violence, she said.
本月早些时候，法国一名警长和其妻子被杀，凶手在行凶后不久就在Facebook上进行直播，敦促支持者们杀掉监狱工作人员、警官、记者和立法者。
Earlier this month, the killer of a French police commander and the commander's partner broadcast on Facebook Live shortly after the killings, urging followers to kill prison staff, police officials, journalists and lawmakers.
芝加哥的枪支犯罪率要比美国任何城市都严重。据警方表示，去年芝加哥发生了近500起杀人案件，而2016年的枪支暴力事件又有所上升。
Chicago has one of the worst gun crime rates of any US city. There were nearly 500 homicides last year, and gun violence is up in 2016, police say.
