A presumption of innocence until proven guilty has a long provenance, not just in English common law, but in Roman law, from which England developed much of its own law. That's about 2,400 years. There are a few times when this was breached. During the witch trials in Europe and the US, one was accused of witchcraft and had to prove they weren't. Similar during the Spanish Inquisition, one had to present the case one was innocent, before even hearing the charges. Another was about 1,000 years ago during the Blood Libels against Jews.
Democrats find themselves amongst witch trials, the Inquisition and anti-Semitic Medieval purges. Fit company for the likes of them.
Do these idiots realize where their efforts will lead?
