I feel like the fact they paid the same party that investigated them is an obvious enough conflict of interest to dismiss this out of hand. Whether the report is actually trustworthy or not, there is an incentive to come to a conclusion that aligns with whomever paid them and that alone should make people question the conclusions being made.

If your leg has a mass of 2kg, 1.1×10^10 J of kinetic energy would require your leg to be moving at about 150 100 km/second not faster than the speed of light.

TLDR: Their math is shit.

Chemist (and biochemist) here. Organometallic compounds of Mercury are primarily dangerous because Mercury ions bond fairly strongly to soft ligands like sulfhydryl groups found near the active sites of enzymes. This can result in the displacement of the metal ions or otherwise disrupt the structure needed for enzyme functionality. Mercury metal OTOH is considerably less reactive. It is not safe to breathe in for prolonged periods of time but it is no where near as toxic as its organometallic derivatives are. Dimethyl Mercury for example, is extremely dangerous. A single drop has 100+ times the organomercury content needed to kill someone.

Do people actually get mad over that? Why?
