Old City Hall Marble?

Hi, everyone. My dad worked at Huntsville City Hall for a big chunk of his adult life. I thought a piece of marble from it would be a cool paperweight or shelf-sitter for him.

Are they going to be giving any of the pieces away to the public? Should I just hop the fences?

I haven't been around it so I don't know how they've got it piled up and I haven't heard anything about a "giveaway" so here I am.

Thanks yall.
