Honestly I'm a bit sceptical of this particular thread. Living in Roswell my whole life I've heard every flavour of conspiracy going, and sometimes a pattern of "accidents" is just confirmation bias - we remember the hits and forget all the researchers who spoke out and lived perfectly normal lives afterwards.
That said I do think there's legitimate scientific debate around fluoridation that gets buried a bit too quickly by mainstream sources. Thats not the same as saying people are being silenced through accidents though.
What specific cases are you referring to? Because if there are documented examples with actual evidence I'd genuinely want to look into it. I'm more interested in haunted objects than government cover-ups personally but I keep an open mind about most things. Just need something concrete to go on rather than a general feeling that the numbers seem off.
