Step 1: Don't shoot yourself. That'll reduce your odds to 1/3 of the average.
Step 2: Stay away from poor parts of town. Add whatever subtext you like. That'll reduce you down to something like a tenth of the average. Bonus: This will also protect you from other forms of violent crime which are several times more common than all gun crimes combined, even counting suicide.
Step 3: If you've gotten this far, you're probably not retarded, so you may be responsible enough to not shoot yourself by accident. If so; get yourself a gun, train with it, and store it properly.
Congratulations: If you've followed all 3 steps, your chances of getting shot (or otherwise attacked) in the United States are now statistically miniscule.
