Nope. Cops don't make the law and are not the final authority on whether or not any given act is a violation of the law.
Those matters are the perview of "juries".

Nope. The law is what it is no matter where you are.

Cops can arrest you for pretty much anything and let the court sort it out.
Yes, a cop can arrest you if he believes that the legal requirements for an arrest have been met.
But as you say yourself, it is then up to the courts to "sort it out", i.e. to determine whether or not you broke the law.
And I am not aware of people getting convicted of failure to conceal merely because they were printing.
Are you ? (specific cases please)
