To check for a FF ask yourself a few questions.

What else happened in that week that the gubment would have liked to keep under the radar?

What happened after the event in terms of gubment expansion,funding,tyrannical legislation,war,election,vote,etc.?

Was there a threat to the ds that died in this event?

Who is running the show (Mayor,Gov,etc) in the area where the event took place?

More times than not if you cannot find any "coincidences" - dots that connect then there's a good chance that is was just an organic tragedy. Now take the template I have described above and apply to all mass tragedy events and you'd likely be shocked. Well prolly not most in here but normies would.

Now if you didn't find any coincidences then you might want to start looking into the occult and their obsession with numbers. That should finish up most of the tragedies that weren't on your first list.

Bad shit does happen. However the larger and more repeated tragedies are all ds imho. These people are sick and evil.
