After looking at what CNN viewers are saying on FB, I firmly believe that they know their viewers are dumber than rocks. Their viewers think, er have been told to think, that it would have been impossible for the deputies to stop the shooter because he had a rifle and hand gun bullets would have apparently dissolved mid flight.
'Course, thinking on it, they could be both.
The only way anyone can make this type of statement, or agree to it, is total ignorance of firearm basics, or simply lying for effect, and hoping all who listen are idiots with no knowledge of projectile launching with a tube and propellant.
