From the time it was adopted in 1791, the Second Amendment went essentially unchallenged for decades. The first gun control laws were created in the South. The first federal gun controls didn’t happen until the 1920’s and 1930’s, about a century and a half after the Second Amendment. Over the past 80 years, the U.S. Congress has written a series of controversial gun control laws. Almost every one of these laws has been caused by outrageous crimes involving guns.
