Market players say the pursuit and offer of market-moving information was allowed to spread partly because of widespread ignorance among brokers and investors on just what insider information is and the lack of penalties to punish leakers. 市场参与者说,以前之所以允许人们寻求并提供影响市场走势的信息,部分原因一是经纪人和投资者对于内幕交易的定义普遍都不了解,二是日本对泄密者缺乏惩处措施。
The trial raised awkward questions over whether leakers like Pfc. Manning provide a public service by revealing secrets or whether such efforts are outweighed by the potential damage to national security. 此案曾引发一些尴尬问题,诸如曼宁这样的泄密者揭露秘密是否对公众有益,或是这样的行动是否抵不过对国家安全造成的损害。
