BDS QC has posted legal election signs in French (see link below) that mention: "Israel Assassinates Palestinian Children. Harper Applauds."
I highly doubt that Canada's Prime Minister has ever applauded the deaths of any children, and as such view the signs as libelous. This is an excellent opportunity for Prime Minister Harper to clear his name and at the same time help children, as I am confident he always does!
