this should ensure that the ultimate goal (or at least part of it) of the breaking of the law is to be a signal to those that make the law or are responsible for it (the majority) that something is amiss and should be changed
Alright, makes sense.
Personally I think there's more ways out of moral responsibility than martyrdom. I'm more sympathetic to the "just following orders" excuse than many. A hypothetical officer than enforces a law they don't agree with can defer responsibility to whoever enacted the law, in my opinion, as they're just a tool in someone else's hands. That excuse doesn't carry weight in the cases of them being overzealous in enforcing the law, nor if they helped it come to pass (voting for it, etc), though.
"All that is necessary for evil to triumph is for good men to do nothing."
I see potential for great danger in the part i highlighted. I do not think it's ok for our hypothetical officer to do nothing about a law he does not agree with. It need not be martyrdom but he ought to do something. At least in a democracy he has partial responsibility for every law in place and voting is only the very baseline absolute minimum of participation you/he should feel obliged to. But raising his voice in the democratic process ans breaking the law sure are different things and the latter should only be an option after the former failed. But in the case that legal actions are not sufficient to right grave wrongs officer joe has a moral duty to break the law. Obviously it is not clear what "grave wrongs" are and in an attempt to ensure that at least the case of breaking the law without a good cause is ruled out i put up the that list of requirements for civil disobedience in the earlier post.
Besides that it is very very hard to give rational proof or similar for
normative statements but i do think at least some basic (natural) rights apply to everyone simply by being human and any violation of those legitimates breaking of law. Those rights are (in my opinion) also absolute, universal and objective moral standards.
edit: wow. spellchecking is great. so many words i can freely use without worrying whether they are spelled wrong or right
