A study by Alex Nowrasteh of the CATO Institute (a libertarian entity founded by Charles Koch, of Koch Brothers fame) showed that over a 40 year period ending in 2016, exactly ZERO foreign-born convicted terrorists acting against the the US originated from Chad, Libya, North Korea, Syria or Venezuela, 6 originated from Iran, 2 from Somalia and 1 from Yemen; none of these 9 terrorists were convicted of murder. Over this same period, Saudi Arabia was the country of origin for 78% of murders caused by foreign-born terrorists; SA , Egypt, Lebanon, Pakistan, and UAE accounted for nearly 100% of all such murders. If Trump's travel ban is truly meant to prevent dangerous terrorists from entering the U.S., why are these 5 countries not on the list? I for one am glad that AG Chin along with other attorneys general are contesting the motives of these travel bans. Immigration and tourism are important drivers of the national and State economies and essential to the survival of our society.
