Just keep in mind with pepper spray that it doesn't necessarily cause the bad guy to immediately stop what he was doing and grab his face. In actuality, even with heavy-duty OC like the police and military use, it takes anywhere from almost instantly to ten seconds or so for the pepper spray to start to burn. Even once it does start to burn, a determined bad guy may still be able to function at nearly 100% capacity. I'm not knocking OC or telling you there's no point; there is. OC spray is Gawd-awful stuff to have in your eyes, and it would probably convince me to look for a credit card elsewhere. Just make sure you get the good stuff, oleo-resin capsicum (sp?), in the strongest concentration you can get. Then, if you have to use it, spray it and haul ass; don't stand there like those idiotic movies and expect the guy to instantly start shrieking and scratching at his face.
