Further IF he says he has the right to say whichever he wants.

As a civilian, he may. And that is still a "may".

If he wasn't involved with his former colleague,

and if his words didin't have a specific motive of an attack,

aiming an outcome.

 

This came to his attention because of his colleague.

Then he chose to justify his/their actions by blaming me,

in an unreasonable way. This is called an attack.

It has a specific motive of an outcome, to 'turn the table.'

 

Freedom of speech applies if it was a simple opinion.

If it's even something lesser, like a strike, law gets involved.

If he is protecting himself and their actions by attacking me *in the public.

He well knows it wasn't just an opinion. Not from where he is.

 

I believe he has violated many of my rights,

he has breached the law. He attempted this 'bullying'

with a specific motive, fully aware of what they've done.
