I think the word “necessary” appears throughout the Criminal Code as a test for all kinds of different activities. I haven't been able to grab one right away from the other justification sections of the Criminal Code, but it is a concept that I know appears in many sections, and perhaps before we're done I'll find a couple of examples for you.
I note that if the word is inserted in the provision where we're proposing to insert it, or where it's come up in this conversation that it might be inserted, it would nevertheless be subject to the qualifiers that the public officer or peace officer would have to reasonably believe it was necessary.
