For state-level criminal issues, it's best to start with a state-specific secondary source on criminal law, criminal procedure, or evidence. That way, you're not sifting through citations from other jurisdictions. However, if one doesn't exist or your jurisdiction, or if you're dealing with a federal issue, a national or federally-focused source is the way to go. Some of the best-known examples in this category are listed below.
Browse or search the below recommendations. Alternatively, you can browse into the Criminal Law practice area on platforms like Lexis and Westlaw, choose secondary sources, and run broader searches with your keywords to retrieve results from a wide variety of sources. Then filter as needed.
