In my mind, they will all be affected by it, for one reason. Actually, the onus isn't on the crown attorney; it's on the police officers to prove that these people are dangerous. For instance, the officer who was shot and killed in Brossard a couple of weeks ago—that is a pure example of somebody who shot and killed a police officer and is now released, waiting for the trial.
That means that in every violent crime or crimes committed with a gun, they would be submitted to that.
