 This is Marine Vet Skip Correa with your home defense tip of the week. One item you should keep in your bedroom at all times is a military-grade high-lumen flashlight. I've raised four teenagers and I've learned that just because someone's sneaking in your window at 2 a.m. doesn't mean you want to shoot them. That bright flashlight will immediately blind the invader and readily identify whether they are friend or foe.
