Imagine this: After a raucous evening out with friends at your favorite watering hole, you stroll home, only to encounter a heinous goon dead set on relieving you of your wallet and valuables. It’s not an impossible scenario, sadly: The Federal Bureau of Investigation’s most recent batch of national crime data indicated there were 300,000 robberies in 2015 alone. Violent crime has been on the decline in the US for decades, but the casual mugging is still a sad reality for many Americans.
