Now, really, what's the effect of that thing hitting a pacemaker, or a tattoo? Metal particles in tattoo's start to overheat during a CAT scan, I wouldn't like to be tattood and hit with that. And another thing, if you were carrying a ray-gun like this, and you know there is a risk of the non-lethal setting not disabling the target right away, wouldn't you rather flick the switch up a few notches?
As for the government in the USA not doing enough, do us all a favour and look at the difference in taxes between a rich guy and a poor guy. And do the same for approx. the same salary in some other country, your own, or Holland. All the forms are available on the web, and if you make that other country your own, or some which language you speak, the whole thing will be done in a day. I can tell you the results of my attempt at filing taxes, but you probably wouldn't believe me.
