I am looking into alternative ideas to keep on me for personal protection and so i am pondering if I need a stun gun? There are a number of choices out there, therefore i am thinking I need to discover if it will be legal to carry one, or if perhaps I must be careful about the level of voltage I buy. Is there a law or regulation on these? I usually go out for walks by myself and I like to run early in the morning, so I wish to have something which I can use in the event of an urgent situation. Exactly what are the items I could choose from?
