> So you're saying it was wrong to assume 9/11 to be a terror attack before 2006?
Osama Bin Laden claimed credit for 9/11, verbally expressing his intent.
> Because until then, nobody had been convicted, and, by your logic, everyone would have been obligated to act with the assumption that no crime had been committed, right?
A crime is something that may be punishable by law. You can know that a crime is committed without knowing who committed it, or what their motivations are.
You appear to be reaching for a way to be right here, but speaking in legal terms, you are plainly wrong. A charge is not proof. An allegation is not proof. You may or may not be right on what his intent was, but the charge doesn't make that case for you, so you can't use it as proof for further arguments.
Paraphrased, your argument is:
* Bobby (a compulsive liar) says that he intended to do it, so we know he intended to do it.
* "unlawful": Intentionally driving a car into a crowd is obviously unlawful
* "violence": yes, equally obvious
* "in the pursuit of political aims": He was a participant in a white supremacist march, and drove into a group of people opposing his politics.
Your second claim fails because intent has not been proven, as it relies on the first claim, which is not provable.
By all accounts, it seems that it indeed was his intent to commit murder by driving into that crowd. I'm not arguing with that. I'm only arguing with the hole in your logic that gets you there, as it is fallacious.
