Yes it is, they may be innocent, but this is exactly the type of story that news networks want. Are you that green?
Also, the report states that they were breath tested, then arrested. There is a serious clue there.......
And STILL in custody.....
Whilst there may be a serious clue, it prejudices a case when the implication is of guilt before even a trial takes place. Natural justice requires impatiality. Comments like "There is a serious clue there..." imply that required impartiality has been lost, and projected in a public domain. Even journalists would not be so green as to imply guilt before a trial: the courts would take a dim view of being so green.
