I would add one that I have seen people vocalize to the media and through the media numerous times. I have heard themsay that an "assault weapon" is more powerful than a regular rifle.

One of these people was a govenor who actually made the distinction between the ability to put rapid multiple hits in a given area and the "power" (energy) of the bullet. He made no bones about telling people listening to that news cast that bullets shot from "one of these guns" were more powerful than those fired from a hunting rifle.
