When involved in a gun related incident if the person using the gun is white and well to do he/she is reported as a "gun collector or gun enthusiast or sportsman". If the person using the gun is non-white and/or blue collar or Southern the national press will refer to the person's "weapons cache" and they will count each round the person possesses.
Everyone gets credited with using an "assault weapon" or an "AR-15" no matter what weapon they used. We will also get the "clip" count. A guy could have a Mossberg Plinkster .22 rifle with 4 mags, an SKS with 4 mags, a CZ-82 with 4 mags and a Ruger Mark III with 6 magazines. He will be reported as having a weapons cache, that includes an SKS "assault rifle", 16 "clips" and over 1,000 rounds of ammunition. The "over 1,000 rounds" includes a bulk box of .22LR - which, of course they don't report and probably don't understand the history of .22LR packaging and sales.
What the world hears is "...a weapons cache that included 4 guns - one of which was an SKS assault rifle - 16 clips and over 1,000 rounds of ammunition." Why?
Because many reporters don't know their hole from an ass in the ground when it comes to guns and because editors want to lead with horror, death, mayhem and terror. In the end, the Press knows better, they simply want to sex it up.
