As we were exiting the airport to catch a cab, we were stopped by two plain clothes police to answer few questions and flashed their badges. One guy asked the usual questions, such as what country were coming from? Why are we in Rome? How long are we staying in Rome? Then, they asked us how much cash we have in dollars and Euros? Before I answered the last question I said, the last question was making us uncomfortable, then he said, if you don't cooperate, we can do it in the back room. I asked him if it is normal for the cops to grab anyone in the airport to ask such a strange question? He said, we do this all the time. I reluctantly answer the last question, and they let us go on our way. Anyone had similar encounter at the airport in Rome?
