While it may not always be politic to point out, the genius of markets lies in their ability to generate value in the aftermath of even the most horrific tragedies. In the wake of 9/11, for example, the security sector became - almost overnight - a productive and patriotic destination for venture and other forms of capital. Even while the sector's "15 minutes" appear to be ticking toward a close, relatively constant market dynamics within the security space ensure that opportunities will continue to abound for those who know where to look for them.
