I have been communicating by email with Matthew Carrol Campaign Director for the Leadnow Campaign which is doing a great job of challenging the Omnibus crime bill. The campaign is organized and as effective as any could be in a challenging situation like this. No doubt a lot of the credit goes to Matthew himself.
If you have a moment, please visit the website and have a look around. It would also be a good idea to send a message to your MP indicating you do not agree with the policies in bill C-10 being pushed through parliament. You can do this easily enough through a handy feature on the website itself.
