A criminal is not some who allegedly breaks laws but someone who is convicted of breaking the law. Even if you were arrested by police you still aren’t a criminal.
If I see them murdering someone, I'm not going to say to myself "That person is allegedly a criminal".
I am allowed to think, to have an opinion about reality.
There's also no need to call them a suspect if you just saw a person committing a crime.
When you haven't yet proved that a specific person did it, they're a suspect. The crime is alleged.
But not when you KNOW it. I'm not saying newspapers should say that or a court should say that. I'm saying I have no problem describing what I see.
Maybe you saw wrong? Hmm?
I did notice that your statement is pretty confident about what I think. No "allegedly" required. No "I suspect he believes X and Y". These imaginary rules don't seem to apply to you.
