Can you provide a citation regarding any of these secret laws that I could be arrested for, or show any example of people being arrested and tried for violating secret laws? Or was all of this done in secret? The only secret "laws" that I've seen come out of the whole Snowden affair were FISC opinions dictating how the NSA can and cannot act with regards to existing public laws.
