I like to write and comment on any interesting and interactive matters. Stun guns using electro-shock technology have proven as one of the most effective defensive weapons. Although the recipient does not sustain major injury, but the impact of the shock make him temporarily paralyzed. Stun guns are very effective for criminal police force members or counter-terrorist soldiers, to neutralize miscreants at short distance. There are other similar varieties weapons commercially available, like battens, mobile phone, and flash light etc. also use the stun gun technology. However, in most of the states in USA stun guns are not treated as gun, thereby individual possession is legal. But, in some states, (NY, NJ, RI, MA, MI, HI and all virgin islands) use of stun gun by private individual is illegal.
