Q: Frankly, Dr. Hawass, are you encouraging tourists to come back to Cairo and to the archaeological sites, or is this still not safe?
A: “Honestly, I have to tell you that if the Ministers of Tourism and of the Interior make a statement to give back the police their power, tourists could come to visit Egypt again. Until now, however, they have not done this. This means that visitors from abroad will have to wait until police officers and Antiquities Police are at every archaeological site once more.”
Q: Until that moment, it is not safe?
A: “I can say this, yes.”
