I don't get why the defense didn't mention that his eCig wasn't a magic flying carpet? I mean how is the judge supposed to know that it isn't if the defense doesn't make this point?
Curiouser and curiouser.
Under English law, and those depending more or less on it, like Canada and Australia, it is called "Burden of Evidence". It is necessary for the defence to raise a reasonable doubt. They do this by presenting evidence sufficient to raise this doubt. Once that has been done the prosecution has to prove their case beyond a reasonable doubt.
I'm sure it exists in US law, but I don't know what it's called.
Say I am watching TV and some kids steal my car and drive past a speed camera at 110mph. Say they do it over the country line or whatever. I report the car stolen, get it back and alls good. Then a month or two later I get a speeding ticket. I can't just stay silent and expect not to have to pay it. I have to go to the trouble of raising that doubt by telling someone that I was not driving the car. The court will make assumptions. It has to. The assumptions it makes are those points of fact and law that are not challenged.
In this case the defence did a good job in proving that a phone was not involved. However they failed to raise a doubt that an e-cig is not an electronic device. To be fair to them it seems this theory was introduced later by the judge, maybe after evidence was finished.
Reading that Examiner article:
Exclusive: Man found guilty of electronic cigarette law that does not exist - Knoxville Business | Examiner.com seems to indicate that the defence team was on the ball but blind-sided late in the trail. I wouldn't like to say without reading the transcript and taking at least a year of law school. But if the defence had crossed their Ts and dotted their Is, they would have submitted evidence relating e-cigs to the law. They obviously didn't do that.
