So here are my favorite less than lethal options:
1. Surefire or Princeton Tech 500 lumen flashlight. This is a great option because it flash blinds any would-be stalker and if needed the light can be used to pummel the face (it will break a nose very easily, a good option fyi). AND you can take this anywhere, including on your next flight. This is why I rank it number 1 of 3.
2. Next up is Jet powered “canned heat” AKA pepper spray. Here’s a link to my favorite. You can sometimes slip this past security (I did last month at San Diego International on United) but the down side is that it’s tough to pack this bad boy around with you. It makes an excellent addition to your key chain, is not expensive, and the jet spray helps mitigate the back blast that could be encountered with down wind deployment. FYI-you don’t want to shoot this into the wind when it’s blowing more than 5mph or you’re toast!
The Taser is a great home defense option and it relatively easy to use. CAUTION: You still need to use this thing in practice and get some training before having to use it in an emergency. Too often people overlook this very simple and obvious issue. Just having it doesn’t make you good using it.
Enjoy and please ask me and the guys questions about any self-defense related issues. We love passing our Spec Ops knowledge your way and I especially enjoy putting creeps out of business.
