This was a great find. I feel that the information has broad enough coverage that it should be stickied. As far as the info contained in it is concerned, should anyone know of a legal update to this law, could you please post it with the judicial code and/or jurisdiction presiding over it (state/county/parish/municiple/etc). Thank you.
Also, here is a graph showing all the state laws for those folks who don't want to read through all of that :
