Another example of RCMP and CSISs glorious due diligence - https://en.wikipedia.org/wiki/S.H.M.B_Noor_Chowdhury
This guy killed the President of Bangladesh and most of his family (women and children included) and is now a guest of Canada and is refused extradition based on a technicality.
I don't condone extra-judiciary killings but Canada absolutely has and continue to harbor criminals.
