I think you described well how a symbol is used within the hate propaganda offence, which is that the intent of the public display of the symbol is to promote hatred. In the reading of the offence, again, it would not expand the type of symbols captured; it would just specify....
Another way of seeing it would be that police officers on the ground would have to know, with great precision, that the symbols are caught by paragraphs (a) and (b), and that if they get that wrong, they are precluded from charges or going forward through prosecution.
That's the inverse. The question to committee would be, do you want that great precision to be on law enforcement?
