Fair enough, so I'll suggest this. If you live in a crime-heavy area, accept that your life isn't something you want to risk on a hack (like retro-fitting bulletproof windows to your family minivan). Securing an automobile against bullets involves some very specific domain knowledge that you're not likely to gain during a weekend project. Specifically, retrofitting your car with bulletproof windows isn't a very good option, because bullets (even a lowly 9mm) can penetrate the thin steel of a car door at close range. Glass capable of stopping the same round will not fit in the channels that support a standard car window, and will be far too heavy for the existing power window mechanism. Cars that offer protection from bullets are purpose-built, have much more than just bulletproof glass, and weigh a lot more (because of armor plating) than your average automobile, which is going to equate to horrible gas mileage. It's simply not a viable option for most people.
