What is reasonable to you may be unreasonable to someone else. That is why we have the rule of law. If the law says I cannot take a photo of the security checkpoint, I will follow the law (although I may see about having that law repealed).
However, that being said, there is no federal law that bars photographing a TSA checkpoint in an airport. See
this post on PV.
Now, if the local laws have that ban, then post signs with the statute citation and be done with it.
