Big mistake and with respect you're uninformed and wrong here.
If he's not convicted then your statement is an accusation of guilt. A false accusation is defamation and it's damaging to the aggrieved party.
False accusations are both harmful to the target and risky for the person making them.
You don't need to be a jury or judge to care about this, for these reasons the AP style guide and practically every journalism outlet takes this matter very seriously.
Now maybe it's 2024, you're a rando from the other side of the world on the Internet and you just do what a billion other social media randos do and you run your mouth. You think your speech doesn't really matter because in practice if you're wrong neither of you is likely to be affected, so you don't need to hold yourself to this standard.
OK fair enough. But if your speech is junk that doesn't matter, why did you open your mouth in the first place? Do us all a favor and if you're going to promote the idea that casual defamation is fine, keep it shut.
