Majory, Frognog is correct. Im sorry to have to break it to you like this but if there are orders or laws in place, you cannot break them without getting done for it. There are plenty of people i know who are still alive today because murdering hem is illegal and i'd go to prison for it.
I look after a large public garden which is a dog free zone. If i get the occasional dog walker in, i politely remind them that dogs are not allowed in there. Some of the reactions i get are quite unbelievable and are very very arrogant at best.
