Quote:75 million tourists visited the United States in 2014. If we want to interview every one of them, and ask them all these questions about their religious views, and do a background check on them, because terrorists aren't going to answer the questions honestly anyway, how much will it cost in manpower and money?


I've seen estimates that the average foreign tourist spends about $7,000 in the United States. Multiply that by 75 million tourists, and the total spending by foreign tourists in the United States is about $500 billion. If we submit every tourist to extreme vetting, what impact will this have on tourism to the United States?


All these proposals should go through a thorough cost-benefit analysis. Wouldn't you agree?
