Another active shooter in MD.

[Wyrd of Gawd]

People usually get attacked when they piss someone off.  So if you don't want to get attacked or shot don't piss people off.

So if we don't want to get attacked by Muslim terrorists then don't mock Muhammad?
Getting "pissed off" is not justification for killing someone. If it is, then we need to have a police state here in the US, along with suspension of the rights provided by the Constitution and it's Amendments.
The responsibility is on the person to not "be a snowflake" about their feelings, just like the Trumpsters like to push. They might have actually gotten that right, only they like blame the liberals for it when in reality it's an American issue, regardless of party.
This is just victim blaming.

There was a tv show on about road rage incidents in the Denver area.  Some people really flip out over insignificant incidents when driving and will even kill people.  If you haven't seen such incidents in person there's a ton of them on the internet = https://www.google.com/search?client=saf...8&oe=UTF-8.

Now imagine how a person will fly into a killing rage when he thinks that he has a real reason to do so.  The average person who flips out and kills someone is venting his rage against a specific person or several related people.  He's different from the serial killer and he would never kill anyone unless the specific victim really pissed him off on a particular bad day.  So be nice to everyone you meet or at least don't be a prick toward them.  

The particular killer in this incident had been simmering for years over a preceived injustice.  So one day he woke up and decided to resolve it.  The victims didn't have anything to do with him other than they worked at a place he had really grown to hate.  So he killed as many people there are he could.  We could have been his victims as well if we had been there.  But if we had ran across him elsewhere he wouldn't have bothered us at all.
