It's a fine line that gadget fans have to walk, moderating our techno-lust just enough that we don't start hurting people. It's a lesson that LG Korea has just learned the hard way after a promotional event for the new G2 caused 20 people to be injured. The "G in the cloud" event in Seoul involved launching hundreds of helium balloons into the air, carrying vouchers for free handsets -- which some members of the crowd tried to shoot down using BB guns. The company has already apologized to those who were inadvertently shot and will cover the cost of their medical care, while subsequent events have been called off. What's wrong with a raffle?
