I'm assuming you want input in regards to the response you got basically saying, "figure it out for yourself"?
Really, I don't know what more you would expect out of a department. As was mentioned above, LEO's are often some of the most misinformed or just plain uneducated when it comes to understanding individual laws. That's not a knock on LEO's, it's just a fact that there is no way they can possibly have a good understanding of every law they are tasked with enforcing. It doesn't make sense that they would go out on a limb and provide you with a legal opinion or advice when their understanding of the law is already suspect, and I'm not sure why anyone would go to them and ask for their opinion or their advice anyway.
Codes and ordinances for most municipalities and other political subdivisions within the state can be found online. If not, then city hall should have a hard copy you can stop in and look at and make copies of. At the end of the day, the only thing that really matters is what is written in those ordinances and it is your responsibility to make sure that you have a good understanding of them, regardless of what a local police officer thinks is or isn't in them.
