Neil Steinberg of the Chicago Sun-Times decided last week to purchase an AR-15 following the Pulse night club shooting in Orlando, Florida. His purpose, he said, was to demonstrate how simple it was and to explore Illinois’ gun laws concerning assault weapons.

When he bought the gun, Steinberg planned to sell it back to the store. However, his purchase was stopped by the gun store, which canceled the transaction during Illinois’ required 24-hour waiting period after discovering he had lied on his background check about his history of alcohol abuse and domestic violence.
