The loner who allegedly killed three people at a Planned Parenthood clinic in Colorado last week committed a deadlier act of terrorism than any attributed to a refugee in the United States since Sept. 11. Robert Dear, the accused gunman at Planned Parenthood, actually took more lives than all refugees combined have done in terrorist attacks since 1980, when the current federal process for resettling foreigners on humanitarian grounds was put in place by the Refugee Act.
