For certain definitions of bad news within the media.
1. No one was killed. Except for the perp, and he doesn't count.
2. The perp wasn't white.
3. The perp wasn't conservative. Being a Somali refugee, it's a pretty good bet he didn't vote for Trump.
4. The perp wasn't a Tea Partier.
and worst of all
5. No gun was used. Except by the cop who shot the perp.
Didn't slow down the knee-jerk calls for gun control though. Beware fake news.
