A misunderstanding of the situation in Egypt
The first is that, having lived in Egypt in 1975-80, he understands the present situation regarding demonstrations. Things were very different then and demonstrations were much rarer. The current situation follows a revolution and a military coup — the society is in turmoil.
The second is that anyone taking part in demonstrations forfeits their democratic and human rights. The right to demonstrate and protest is a basic democratic right and there is no evidence that these Irish citizens did other than exercise this right.
