we are not sure whether this has made him some enemies

虽然这句是疑问句,但是,
whether 后面引导的是陈述句.
在陈述句中一些用some
再问： 也就是说 因为 this has made him some enemies是陈述句 所以用some？ 那 The police are aiso interested in knowing if the victim had any enemies. 又怎么解释呢？
再答： if the victim had any enemies 这名被害者是否有敌人， 是疑问句。所以是any 从句是完整的句子，里面的any 或者some 是看从句的性质的
