Well, yes you can. Even when there is a court case, the burden of proof is pretty high and plenty of people who have been found “not guilty” aren’t innocent. Look at OJ Simpson, won the criminal court case with a “beyond reasonable doubt” burden of proof, lost the civil case which had a “on the balance of probabilities” burden of proof.
The justice system, since it is the extension of the power of the government, should absolutely have a high burden to prove before it can punish or incarcerate members of the community.
But that doesn’t automatically mean that society and individual citizens should hold to the same standards. Especially in cases where some of the alleged behaviour either wasn’t illegal (but very questionable) or is beyond the statute of limitations. If you take a look at a case closer to home, Stringer if he was doing what his wife alleged wasn’t doing anything illegal. However, society can still absolutely have a view if his sex with under 18’s makes him suitable to represent us in parliament.
