New figures released Friday reveal that Customs and Border Protection (CBP) officers searched 30,200 devices -- an increase of about 60 percent year-over-year -- between October 2016 and September 2017.

That averages out to about 2,500 searches each month out of more than 397 million who crossed the border -- or less than 0.01 percent of all international travelers, according to the agency charged with enforcing immigration and customs rules at the nation's ports of entry
