400 milliamps Is Enough To Kill
So, it seems from reading the comments that the defenders of this "toy" say it's harmless. I did a little research:
This person here says he built a disposable camera taser that generated at leaset 400mA (milliamps) of current: http://staulkor.com/node/4
"Yes, those are burn marks around craters created by a disposable camera taser. This thing has some serious power. I pulled out my fancy multimeter and tested this thing out. With the camera I bought, I charged up the capacitor for about 5 seconds, and measured the DCV and mA in the capacitor. I was shocked at what I found. This thing was at 330v and 400mA only after 5 seconds of charging. I kept my multimeter probes on the capacitor and watched the numbers. It kept climbing, slowly but surely."
And here, this person says that 70mA (0.070 amp) is enough to Kill

It isn't the voltage, but the amperage that kills.The damaging effects of shock are the result of current passing through the body. This current depends on voltage applied and also on the electric resistance of the human body. A current of .005 amps is painful. At .010 amps involuntary muscle contractions occur. Loss of muscle control occurs around .015 amps. A current of greater than .070 amps can be fatal. It only takes .070 amp to kill ! Current(I) = Voltage(V) divided by Resistance(R)"
Now I'm not saying that arresting this kid wasn't an over reaction, but I wonder how some of this person's defenders would feel if this so called "Toy" had killed a member of their family?
