JOHN GRANT BEAUTIFUL
The point of a petition is to basically let someone know that people are not happy with what they are doing, and if enough people protest the government you can get them to change their decision. This is especially true with a politician. They know thee job depends on votes and if they are going to gain enough votes to secure their job they will do it even if they truly do not agree with it.
You must apply for a permit to protest at least 30 days in advance, or if there are delays you may not have a permit on the day you have told your protesters to show up, to truly insure you have time, apply for the permits at least 60 days in advance.
