Arrests are not made on popular votes. The FBI was the legal authority to investigate and decide on charges, and they clearly said nothing was near a legal threshold to charge.
Hillary complied with them, didn't fight in the courts for years, didn't obstruct. The only places making such nonsense noise was certain media outlets.
The only accurate info the public has is from the FBI statements (and a few later FOIA releases). Rad those to get a correct idea of what is known.
It is actually low by 6%, if you read “disagrees withe the decision not to recommend charging her with a crime” as equalling “believes she should be arrested” (though I suppose it is theoretically possible to think the FBI should have recommended charges but the DoJ should still not have charged, or to not understand that arrest is a natural consequence of criminal charges.)
