A few nice National Security images I found:

U.S. Ambassador to EU, Clayland Boyden Gray, visits University Ghent, Belgium for debate. He was constantly under surveillance of Belgian National Securityagents, which was very impressive to witness. He came to UGent to talk and discuss U.S. policy and international relations (especially between U.S. and EU).
