Here's something interesting I've learned from having classes taught by several deputy DAs with the Jefferson County DAs office:
There are literally thousands of pages of statute in the State of Colorado- out of every law and ordinance, there are dozens that aren't prosecuted. There are so many laws on the books that DAs have flat out said "I have never seen this prosecuted, ever." One was coming from a 17 year veteran prosecutor. So no, I'm not surprised that no one has been prosecuted under these laws (yet), and if no one ever is, well then it just turns into another stupid, useless law that should be gotten rid of.
