枪击黑人男孩案引发全国讨论

Andrew Lester, the 84-year-old white man accused of shooting Ralph Yarl, a Black teenager in the US Midwestern state of Missouri, pleaded not guilty in his first court appearance.

84岁的白人男子安德鲁·莱斯特被指控在美国中西部密苏里州枪击黑人少年拉尔夫·亚尔，他在首次出庭时表示不认罪。

Lester was in court Wednesday to answer charges of first-degree assault and armed criminal action in the shooting, which has attracted presidential attention and renewed national debate about gun policies.

莱斯特周三在法庭上回应了一级攻击和枪击中的武装犯罪行为的指控，这引起了总统的关注，并重新引发了全国关于枪支政策的辩论。

Lester turned himself in Tuesday and was later released on bond after agreeing to relinquish any weapons and have no contact with Yarl or his family.

莱斯特周二自首，并在同意放弃任何武器和与亚尔或他的家人没有任何联系后，被保释。
