I’m serious, whether you live near Ferguson or not, get a gun. With the waiting periods, limited ammo supplies, and other issues, it’s better to get a gun well before it’s needed than to wait for the last minute. Then, once you have a gun, spend time at the range, weekly or more often, and get another gun. Get a .22 pistol and a bigger pistol. Get a .22 rifle and a bigger rifle. Get a shotgun or two (12 gauge only). Learn to shoot them all well, and do it all before the riots come to your neighborhood.
A good firearm responds to danger at 122 fps or better. A good 911 response is 5 to 10 minutes. Get a gun - as soon as possible. Learn to use it, learn your local laws, and keep your firearms safe but handy.
You might want to take a crash course on the velocity of bullets.
Fixed it
Hopefully. Although my SUV can outrun such a bullet.
