One other note..... searching google is not nearly enough to frame this broad issue into perspective. Most if not all of the state-hosted websites with all public statutes online, do not allow internet search processes, which feed the search engines such as google, to catalog all of the site data recursively due to excessive use of host resources; so the most relevant documents themselves will not be found also. Beware sites offering opinions but no letter of law. Some states don't even have the public statutes online, and some publish only portions. Even worse, sites with OUTDATED and otherwise inaccurate legislation, major danger. That is the main reason you cannot see a short synopsis explaining why there is often a precedent to charge someone under.... at a minimum there are 50 different variables for each person reading in the States, and surely more based on...... priors, penchant to be in the local radar, all kinds of stuff.
You'll have to assemble your own understanding if you want to be decisive about the issue. Obviously you're not at the current time, due to the request for more information or "proof". Not a bad thing, just indicates this is one you'll have to put some time into, the statutes are long and can be difficult to read. Often the online search engines suck as well, not returning the expressions you've searched for.
Past that, for precedent, a Lexis-Nexis search or Westlaw (does that still exist these days?) and other specialized institutions will reveal cases for you to research.

No gimmes on this one brotha. Have at it!
