I believe that incident was in the Dominican Rebublic. But, yes it reminds us that it could happen anywhere.
We went on a cruise once and we went through a popular island. The taxi can drivers were fighting and frightened us. One time we went to another country and they were having all sorts of problems and there was much tension in the air.
We went to a country once (via cruise ship) and that particular country takes your passport when you enter. Then we had very concerning problems on a tour. Of course in the back of my mind was I didn’t have my passport.
I’ll never go there or any country that confiscates your passport at the boarder again. (They give it back...but still...no way)
One has to be very careful.
I’ve gotten more aware and extremely careful.
