Accusation: We need to deport all undocumented persons and seal the border in order to prevent terrorist attacks.
Actuality: Seventeen of the nineteen 9/11 terrorists were in the country legally on student visas – the other two had overstayed their visas. Terrorist attacks are usually planned and carried out by operatives who have been in a country for some time. By legalizing the undocumented population and creating more visas for workers to enter legally, we better know who is in the country and who is coming, thus making us a safer nation.
