No.
You are saying that you don’t have to believe women until a court agrees with them. That is technically and legally true, but it makes you an asshole.
Other people, thankfully, believe credible accusations without waiting for the cops. Nothing people did was outside of “Alerting people in a public venue to the existence of a credible threat.”
That doesn’t mean all people should be called a rapist in all situations. This situation? You sound like an idiot saying no one should have complained.
