I already posted this on TD but might be better over here.
There was a tweet thread showing an account that had some weird videos that focused on Irish politics and another account with the same name where the security cam footage of the bombing showed up, link below.
Also the IRA was known for clearing out civillians before blowing something up. I saw someone comment about this on news channel, link below. There is also the significance of the bomb going off on Christmas day which ties to the IRA's Catholic roots.
Some of the other pedes on TD confirmed this was the MO of the IRA to clear out civillians.
It is also highly likely this was a DS asset from back in the day when they were causing trouble in Ireland.
Thoughts?
Sauce:
You've got a good point, Verbum, the DS is insidious and they probably did have plants in the IRA. I bet they hated it when the IRA was reasonable and they couldn't blow their cover by advocating for rampant murder. Good on ya, IRA!
