Non-lethal personal protection ...

It's all about the juice ... a few million volts should do the trick and slow the bad guy down. Take a look at the StunMaster Multi-Function 4.5million volt Stun Gun. Emergency red light and 110db audio alarm, rechargeable lithium batteries. About $110 plus shipping.

Plug the probes into the bad guy and watch 'em fall.

No bullets, no blades.

Works well on hippies.
