A: It depends. Usually they would be sentenced to up to 5 years in prison. But if the factory is making goods that help Israel to defend its citizens, the seven walk free.
Jonathan Hoffman writes at CiFWatch:
The seven broke into the EDO MBM armaments factory in January 2009 at the time of Israel’s Operation Cast Lead in Gaza. The factory was exporting military equipment to Israel. After being directed to acquit them by the Judge, George Bathurst-Norman, the Jury duly obliged, accepting their defence that although they had committed a crime, they were doing so in order to prevent the greater offence of Israeli “war crimes”. In his summing-up, Bathurst-Norman made no bones about his ill-informed political prejudices, saying (according to The Guardian) “You may well think that hell on earth would not be an understatement of what the Gazans suffered in that time.”
One wonders what other crimes anti-Israel activists will be able to commit without fear of punishment.
UPDATE: Melanie Phillips has more.
