Imagine if he had died from the heart attack. All we would have ever heard was that a "CHL holder died in custody after being arrested for threatening children at a park with his concealed handgun. The CHL holder was scheduled to be arraigned on charges of deadly conduct." And he would have been a poster child for the Brady Bunch.
