Yes, it is very sad. This will further weaken secular interests and increase the Islamic hold on the government.
Normally I agree with the old saying: "When in danger
, when in doubt, hoist the anchor
and bugger on out!" In this case that would have been unwise. Particularly with it known that Erdogan was in the southern area, anything that might look like it could be an attempt to smuggle him out of the country could be greeted violently. Even without that the Turkish military is no-nonsense, and with the extra tension of a coup, disobedience of a military order could get very ugly results. Tourists were never targets, so don't make yourself one.
