New row over Kingsmills massacre after some unionists shared controversial cartoon about the atrocity online

Another row has erupted on social media over an image related to the Kingsmills massacre. The south Belfast DUP MLA Christopher Stalford shared a cartoon satirising Sinn Fein's equality agenda - and it was shared by other unionist politicians including Ulster Unionist Doug Beattie. It was headlined 'Sinn Fein's red lines' and showed 10 streams of blood coming from a van like that used by the Kingsmills victims. The cartoon has since been deleted by Mr Beattie and Mr Stalford after he was contacted by victims families. So is this legitimate political commentary - or cheap point-scoring and an insult to victims? Vinny spoke to the UUP's Doug Beatttie and asked him if sharing the picture in the first instance was a mistake.
