Did technology help beat the house?

ISo there were these people who attached a laser velocitimeter to a cellphone, used it to measure the speed of a roulette wheel ball and the roulette wheel, photographed the position of the ball at the time, phoned the data home, crunched a best estimate for a range of likely landing spots and won more than 2 million in 2 days. They were arrested on the second day, but later released and now they have their money too, because they weren't interfering with the wheel or the ball. No doubt casinos will all install cell-phone blockers soon. Which will work until someone comes in with an organic processor and does everything on-site.
