Douglas Bodrero

Explanation:

Douglas Bodrero served as vice president of the IIR Board of Directors during his tenure in this position, working on the implementation and creation of various counterterrorism strategies and training of qualified personnel to address such issues. He worked with the State and Local Anti-Terrorism Training Program's instructional staff, making the strategies used in this program recognized worldwide, as the strategies were carried out with admirable subtlety and enabled the detection of extremely hidden terrorists.
