"A bit further up on this thread, somebody pointed out the difference between a breach of law and breaking the law. I questioned this and it was, as far as I can see, repeated."
'Willie'

I might suggest you can't see very far 'Willie' or your determination to score a cheap point is making you blind to what I actually posted
Please go back and re read; I really can't be bothered to have to explain again that a breach of the law and breaking the law are synonymous and that the people who chose to withhold their council tax as a form of protest were well aware of this and were prepared to accept the consequences of non violent direct action

" Tax resistance can be a form of conscientious objection (for example, some pacifists refuse to pay taxes that pay for war).
Tax resistance can also be a variety of protest, or a technique of nonviolent resistance
Tax resisters may accept that some law commands them to pay taxes but they still choose to resist taxation."

For your information 'Willie' there is a literary device known as synonymia; while it is more commonly used to add force or clarity it may also be used simply to avoid repetition in the same sentence.

"but nowhere in that, or I believe any other, is there a difference between a breach of the law and breaking the law. You can be guilty of letting society down either way."

You really are flogging this wilful misunderstanding aren't you?

The Salt Satyagraha, which began with the Dandi March on March 12, 1930, was an important part of the Indian independence movement. - whatever the argument about the current state of Indian politics I don't think Gandhi can be dismissed as letting his society down
