Massachusetts paraplegic charged, attempting citizen's arrest on alleged molester

Ok, so 'ordering' someone to sit down is a criminal act?

It is if you don't have authority to order someone, just like detaining someone without authority is unlawful detention.

Threatening behaviour, pointing a bat at someone?

Yes. Simple isn't it.

Nope, more like indicating to me (if he was pointing at me) that he wants his point (s) heard.

In what way does a bat increase your audibility?
If a bat has no actual effect on the function of ears or mouth then it has no place there in that capacity.
If it is not there in that capacity and wasn't there as they were playing baseball together then it has no function other than to threaten
