In the OPW's response to Mr. Doyle, it claimed:

Kilmainham Gaol is a national monument and an iconic and much respected site in the context of the national independence struggle in particular. The fact that it is also a grave location adds a significant resonance to its penal and historical significance. There is a strong opposing view to the current campaign that believes the graves should not be disturbed, and the remains should be left within the confines of the Monument.

Who are those with the "opposing view"? In my opinion, the families' views should take precedence here. I will play devil's advocate here. If it is known who holds the "opposing view", is there ongoing communication with them other than through the Department?
