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.
So such polls are at best outrage fodder.
As the OP said, we have laws. Not mob lynchings.
