I said the same thing on Facebook. But a friend in SoCal said he actually saw it on CNN. However it was recently in context of the Sandy Hook discussion. He didn't see or hear about it when it happened.

most active shooter will kill themself the first sign of resistance.

No you won't see this in the mainstream media. It doesn't meet their agenda. So to counteract their bias, we need to spread it far and wide by every means possible.
