Fair enough Hawk, I guess you have to expect the unexpected as we never know what's around the corner.felons cant have stun guns. and if we are talking knives i can use any kinda knife no matter how cheap it is. im been practicing marial arts for over 20 years so i know what im doing. those pepperbal guns do work. plus you could load one pepperball and then load one of those steal balls right after it so you get shot with a pepperbal then you get shout in the head or chest with a solid ball its gonna give you time to react. wether is run or whatever else you decide to do. I know what im doing. never lost yet
Are you concerned for your mum's safety or your own safety (maybe both ?) do you reside in a dangerous area known for serious assaults and attacks.
