The "enforcement notice" and definitions they are establishing in this bill are being done maliciously with the intent at harming citizens, but as I said regardless of what interpretations they invented, once this bill is signed; the state has no authority to penalize anyone who acted in manners prior to its signing.
"Hey uhh you know that Honda Civic you owned for 10 years that you bought from a dealership in state? Remember when we talked about making it illegal to own and gave out a toothless enforcement notice? Yeah uh, well now with this bill we are making it illegal to have owned for that time so HAHA gotcha citizen!" It does not work this way.
