Please stop twisting what I say to suit your narrative. Every bomb that ever went off had a 30 minute warning of where. It is obivous you posted here to show your backside and your anti Catholic rhetoric I hope you have to answer for that one day.
Well, apart from the time the IRA gave 15 minutes warning, and got the location wrong by 15 miles.

Honest mistake though. Human nature and all that.
