Your original comment mocked Duffy for not knowing "where the heck he actually lives."

The issue of where the heck Duffy actually lived - and all that comes with that (where his principle residence was located, and where it wasn't) - were insisted upon by Harper.  

Harper's legal advice found Harper's rationalization for Duffy's 'PEI residence status' to be ludicrous and told him so.

Yet Duffy went through a long criminal trial and suspension from his duties - and Harper and Wright not only escaped that, but had/have apologists still blaming it all on Duffy.
