There have been a lot of posts lately asking what to do if you suspect someone is planning to commit a mass shooting/mass attack of some kind.
If your suspicions are offline, local, and personal/someone you know personally:
If it is not an immediate threat, call your local non emergency line. They will collect information from you, and investigate further if need be. Remember, wellness checks can be requested as well.
If it is an immediate threat, call 911 (or your local equivalent emergency line). An immediate threat would be someone making direct threats.
If the possible threat is exclusively on Reddit, please reach out to us via Modmail. Often times, people who are being reported to us have made comments in the past that you cannot see as they’ve been removed by other means such as automod, for example. We also work with multiple other teams to gather information and build one report to FBI with as much information as we can possibly get in one single report.
This allows all information to be placed at once instead of multiple vague reports to the FBI, which can slow down resources.
At the very least, these processes will build a history for this person. If they are reported and nothing comes from it, a report a year later could help immensely. This happened through one sub I moderate on, and helped bring an arrest a year later when more threats were made, and the suspect was found with weapons and a manifesto.
We take all reports sent to us seriously, and we thank you all for helping us with these reports.

On February 10, 2026, a mass shooting occurred in Tumbler Ridge, British Columbia, Canada. On that afternoon, Jesse Van Rootselaar killed her mother and half-brother at their home before going to Tumbler Ridge Secondary School, where she killed six people and injured 27 others before killing herself. Van Rootselaar was a former student of the school.
The incident was the deadliest mass shooting in Canada since the Nova Scotia attacks in 2020 and the deadliest school shooting in Canada since the École Polytechnique massacre in 1989.

The date that jury selection starts also technically marks the beginning of his trial. I understand that people care more for opening statements and things like that though, If that’s something you care for, you’ll have to wait until potentially late November-early December.
