“Answered by Rosa Parks 50 or so years ago.
Is it unconstitutional for a restaurant owner to throw out a bum?”
You clearly have no idea who Rosa Parks was and what the issue was.Neither do you. OJ is NO Rosa Parks.
The issue was Public Transportation and State Action and invidious discrimination on the sole basis of race, in violation of the 14th amendment.
So what was the answer?
Is it unconstitutional for a restaurant owner to throw out a bum (like OJ)?
What law was broken by the restaurant owner when he told OJ to get his murderous ass out of his restaurant? Huh?
And what law school did you flunk out of?
