Of those, “the number of known suspects in mass shootings which are trans is under 10 for the last decade,” which translated to “1:880 [or 0.11%] of the 4,400 shootings” they recorded, he said.

For the US, “About 1.03% of the nation’s adult population identifies as transgender, according to the Household Pulse Survey.”

So it seems people who aren’t trans are approximately ten times more likely to go on a mass shooting. Am I missing something?
