Let me guess: They are paranoid about another mass shooting happening, yet have done absolutely nothing in terms of security at Virginia tech, no armed security guards, no single entrance, no armed teachers, no armed anybody because nothing is more important than allowing another fish in a barrel shooting to occur so the left can have another reason to unconstitutionally infringe upon the 2nd.
Here’s a better guess: The idea of a foreign national walking around armed with anything more than a pocket knife is preposterous.
