The City of Baltimore data portal claims otherwise.

http://www.baltimorecity.gov/TermsofUse.aspx
"OpenBaltimore is licensed under a Creative Commons Attribution 3.0

They also include in the Disclaimer, "Commercial use is prohibited without
the prior written permission of the City."

Either one of those is a big red flag.  Can you publish their assurance to
you that the data is actually PD? You'll need to publish compelling
official documentation from the city that can override their published
license.  The license details on the Baltimore data portal web site make
that data an absolute, "NO GO" in my judgement.
