not all scientists are neomaxzoomdweebie egghead victims of 97 lbs.

some are weapons scientists/engineers and are highly combat trained and situationally aware, and dont have a comfort space you can exploit.

these are the ones that will not go quietly.

Hey poster. How is this not BS what are the actual stats? this sounds more like a diversion move from Fox.

rolph•1h ago

consider that there are a lot of quite old scientists that are overdue on lifespan.

consider also that knowing you could be targeted, from the start, not because of this supposed trend, but because thats the nature of the job.

the government and its agencies are not above faking decedence to cover an asset of extreme worth.

ordinarily an obituary can be found.
