Having your eyes pecked out by ravens is not actually lethal.
My problem isn't if it will or if it won't permanently blind the target if hit in the eye. I don't actually know on account of not being demetedly sick enough to try to find out. My problem is that it is so EASY for a schoolkid to get the bits and knock one of these things together. Muggers could incapacitate their victims for a piece of equipment costing a few Euros by the time the Chinese get in on the act. Is all this security making us any safer, one wonders.
Call me a communist or I'm getting into the designer laser safety eyewear business pronto. Who'll fund my quest?
