Madam Speaker, that is precisely our fear. The apparent expansion of the definition of self-defence, because it is somewhat unclear in the legislation, to include a person not being in harm's way but defending someone else who is in harm's way could, we fear, lead to unintended consequences. The example I gave was of the ice cream truck being held up at gunpoint, which ended peacefully. No one was injured.
However, if this law had been in place, one could imagine that a citizen from a dwelling nearby may decide to take action using self-defence as the reason for taking action and cause much greater harm than was caused at the time.
