Do entry checks stop terrorists?

I’m afraid that it’s impossible to stop terrorist. Some insist that a new immigration procedure obliging most foreigners to be fingerprinted and photographed works as detterrence. However it’s impractical to eradicate terrorism.

First, difficult to crack down on terrorists who pose general residents.

Now, we are living in so-called high tech age. It might not be necessary for potential terrorist to enter Japan. They can procede their activity as remote operation without entering to Japan. In this case, immigration procedure is useless. Way back when, North Korea used Radio signal on air to send message or direction to espionage agents who pose general residents in Japan. I believe that more sophisticated technology would be used in high tech age.

Second, full of inaccurate data. The lists are believed to include one compiled by the U.S. government and contain the names of 750,000 “suspected” terrorists. I’d like to express concern about how much we can trust its accuracy. The hostile structures are different between U.S and Islamic terrorist or between Japan and North Korea. Does the list contain “suspected” terrorists Japan intends to refuse from entering the country? How often is the list updated? I believe that this procedure heavyly rely on the inaccurate data.

In conclusion, I doubt whether it will stop potential terrorist from entering the country.

They can operate remotely. Besides, the lists are not trustworthy.
