Nothing was proved. He was given the benefit of the doubt and released. (什么证据也没有找到,他被假定无辜,被释放了。)
give the benefit of the doubt指在一个具体情况下,一个人存在犯了罪或不曾犯罪两个可能,但缺乏可以确定他犯罪的证据,此时只能相信他自己的话,假定他无罪。
在日常生活中也可以用这个短语:
Jack’s grade in the exam was much higher than usual and he might have cheated, but the teacher gave him the benefit of the doubt. (杰克的考试成绩比平时高出很多,可能做了弊,不过老师宁信其无,没有追究。)
