Nope. The Crown appealed the acquittal. The decision was overturned and and the marshmallow launcher got 18 months. A further 9 was added onto the sentence as the tosser was using white marshmallows only, and this was construed as a hate crime.
In a stunning turnaround, the marshmallow thrower, Rapy McStabface, had this sentence commuted and was immediately released. It was revealed he was a recently arrived illegal immigrant with a stolen British passport which had belonged to the father of a recently raped and murdered 6 year old girl from Manchester. A man fitting the description of the accused had been sought in connection with the murder. The judge found that it was not possible that this man could have been guilty of anything so heinous, and awarded him 3 bags of white marshmallows in damages.
A friend of the family of the deceased girl was instead gaoled for tweeting mean words about Mr McStabface.
