Re: Publishing Photographs
since this is obviously for classwork, how about you answer your own question.
Explain how printing a pic of people intentionally holding up a banner suggesting they are being treated improperly would be considered defamatory. Who is being defamed and how?
I am not an attorney and any advice is not to be construed as legal advice. You might even want to ignore my advice. Actually, there are plenty of real attorneys that you might want to ignore as well.
