I'm not exactly sure what this SRWT even means, but it's probably some kind of "You Don't Need Guns To Kill You Can Do It With Knives Neener-Neener!" taunt. At any rate, Piers Morgan wasn't amused, and promptly banned Loesch from his show.
Regardless, if your first instinct upon hearing about some horrible act of violence is to take to Twitter to taunt your political opponents, you might want to get some help.
