Professor Anthony Staines:

This comes back again to the idea of non-essential travel. If one needs to travel for work, then one needs to travel for work. That is essential travel. If one can work at home, one does not need to travel for work. Then it becomes non-essential travel. If one needs to care for somebody, I would argue that it is essential travel.

This is not about having gardaí standing back to back, linked arm to arm around the borders of the counties. Even if we wanted to do that, we could not do so. This is about asking people in the counties if they need to travel. If they need to travel, then off they can go with the blessings of God on them. If people do not need to travel, then they should not travel and should stay in their county. That lets us pick off the epidemic in pieces.
