I'll make this quick.
When I read your bill for the first time, I told myself that, if a judge must render a sentence for a person who impersonated a police officer in order to commit another offence, he will probably consider the impersonation to be an aggravating circumstance and take that fact into account when handing down a decision. I think that goes without saying.
Have you looked into the case law of sentences related to section 130 of the Criminal Code? Have you found cases where, under similar circumstances, the judge did not deem this type of behaviour to be an aggravating circumstance?
