` :::Well, thanks for that. Still, the term has the implication of ``happening accidentally, without planning``, which is not the case here. Therefore it seems to be a slight misinterpretation of the facts. Moreover, it's unclear whose interpretation it is: the reporter's/editor's, the official's or perhaps Tsarnaev's. So I would rather not use it here - but leave it for you or others to decide. )   `
