If there is a law I truly don't believe in... I just break it... I have no fear of the police as you put it.
If the punishment will be severe enough and enforced commonly enough you will not break a law that you don't disagree with, don't bullshit us just to get your point across.
And I don't hold you or me to any standart it just basic physiology and logic, if tomorrow a new law will determine that driving on a highway is limited at 30mph and a 10 year jail time you will not do it, the risk vs reward will be too great.
The exception to that rule is breaking the law as an act of defiance and trying to create some political change, otherwise, regular law obeying citizens obey the law mostly due to fear.
Don't mix it up with laws that you think they are sensible and you obey them because you agree with them.
