There are so many reasons to carry pepper spray or a stun gun. Just check your local laws on pepper spray carry and stun gun carry to make sure there are no restrictions where you live. Never use a stun device near a gas station, propane, fuel, or flammable fumes. Use your pepper spray with caution on windy days so you don't have any blow back into your face. And, there are many uses for security cameras to keep an eye on things when you can't be there. A surveillance video could tell you a lot of things you didn't know were going on and help put a stop to unwanted behavior you weren't aware of.
