He gave out supplies initially, but, when the neighbors returned with a crowd, he explained that he needed the rest for his family. The crowd turned antagonistic. The man scared them off with a shotgun, but it wasn't long before they returned throwing bricks through his windows in retaliation. He left soon after with as much of his emergency supplies as he could carry.
“Cartridge firearms are compact vehicles for change that have shaped modern history. The righteousness of their use is entirely up to their users, since like any other tool they can be used both for good or for ill. A firearm is just a tool with no volition. A rifle is no different than a claw hammer. To wit: A hammer can be used to build a house, or it can be used to bash in someone’s skull—the choice of uses is entirely up to the owner. A bulldozer can be used to build roads, or to destroy houses. A rifle can be used to drill holes in paper targets, or to dispatch a marauding bear, or to murder your fellow man. Again, the choice of uses is entirely up to the user. ” – James Wesley, Rawles, in  Tools For Survival
Again, the reason we tend to look sideways at those who get a little too into prepping for an apocalypse is because of their smug optimism.

Car electricity runs on direct current, but almost everything else is alternating current. What you need: an inverter. Some cars have them built in, but you can get one at a store for less than $40. Use the clamps to attach the inverter directly to the terminals on your car battery. Let the car run at idle and you have 110-volt AC power for as long as you have gas. With a 300-watt inverter, you'll have enough amps to run a laptop or even a television.
