We are a country of federal, state, and local laws (and international treaties, for that matter). So when someone asks, “What’s the Law On …,” law librarians and lawyers need to show laypeople how to Find the Law(s).
NPR has done that for you with Body Cam Laws (but, note that laws change so you will need to update this research each time you need accurate data.)
“Piecing Together America’s Patchwork Quilt Of Body Cam Laws,” posted 2/25/16, at NPR’s All Tech Considered.
LLRX dot com is still a fabulous legal research resource:
State Legal Information Census: An Analysis of Primary State Legal Information
And if you can’t get enough of law librarians’ legal research blogs, Justia still has the best round-up, at their blawgsearch website.
Look for the 7th edition of this important legal research resource, National Survey of State Laws, which is used by lawyers and many other legal researchers. Visit the Hein Blog for a July 8, 2015, guest post by the author, Richard Leiter.
