This video address the hot topic of the use of weapons in a grappling/real world confrontation. Although this video takes place in a controlled atmosphere I am fairly confident when I say I think I could have won this altercation regardless of the taser.
The stun gun is 1 million volts and has multiple contact points (I almost shocked myself in the opening part of this demonstration). I must be very clear when I say I do not recommend doing this at home nor do I condone hazing or the use of self defense equipment on others. I am an professional, and I suggest you take my word for it.
