that is not the typical use of the word 'occupy', like occupying a toilet.
It is. They were in the space. They are occupying the space such that nobody can use it without having to pass by an angry, unhinged, lawbreaking protestor.
You think that when someone occupies a country that they are the only ones who can use it? The point is that they are in the vicinity and capable of leveraging against others there to an undue extent.
They occupied the space, and made anyone else who wished to also occupy that space have to deal with their hostile presence.
Where is this "using the space for transit" wording
It's implicit, as using the space for transit is the only kind of use that is not loitering. In that specific space, any kind of loitering would be construed as intimidation, harassment, or protest.
If you can figure out another use for that space that would not obstruct the business, or be an act which in action delivers a message of disapproval or intimidation, then by all means add that to the list of allowed activities. Incidentally, the location was a street, which was chartered specifically as a space to be used for transit.
Maybe kids playing kickball? ... But only that assuming they weren't put up to it by adults for the purposes of discussing protest against the business or it's clients.
As soon as it becomes an action whose nature includes disapproval of the business, it needs to go elsewhere.
And praying is considered protest.
When it is done as an act of protest, yes. Prayer can be done as an act of protest. Zero acts of protest of any kind to include prayer we're allowed there.
She was arrested for protesting.
She disrespects all who would pray by using prayer as a form of intimidation and harassment.
It's like saying "it should never be illegal to give someone a flower, they should not have been arrested for that" when the delivery of the flower is "frozen hard and stabbed into an eye."
It does nothing to defend the actions and everything to make them that more repugnant, in trying to profane prayer to use it as a lever against such an order. I'm not religious and even I see the profanity in that. Even the bible she claims as her basis for behaving in such a repugnant way says that is profane.
