Edit 2: IMPORTANT This thread will be locked if you all continue posting photos of people you think could be the shooter. We don't want to lock it, so just read this comment and knock it off. Report the idiots you see violating these rules -- it's a huge help.

Edit: We are aware of a manifesto being circulated. Please do not post it here until it is confirmed as connected to this event. Anyone posting the manifesto, naming the suspected shooter or victims (before confirmed by Police/media), or sharing photos/videos of identifiable victims will be banned without warning.

Quick reminder to everyone about commenting during major situations like this.

• DO NOT post about police movements. In other words, if you are listening to scanners and radio communications of emergency personnel, hold off on sharing the play by plays.

• DO NOT share the personal information of alleged suspects or victims until the identities are confirmed by the police or mainstream media.

• DO NOT post identifiable images/videos of the dead or dying. Reddit is one of the most high-traffic sites in the world, especially in times of crisis. No one should find out that their loved one has died in a reddit thread. To clarify, you can still post images and videos of the incident, just no closeups of someone's face as they die.
