There are a number of technologies being explored by the U.S. government for the sake of national security. One of the best documents to review those proposed technologies is the 2012 budget request from the U.S. Department of Homeland Security. This document not only reveals technologies and activities given the highest priority by DHS, but it also hints at a focus on development of future technologies and gives a glimpse of the direction the government is headed in strengthening the nation’s borders and bolstering the nation’s security. It’s important to stay aware of these activities, because while the legitimate and appropriate use of such technologies would certainly lead to more secure borders and a safer nation, the inappropriate use of many of these same technologies could potentially conflict with the liberties of American citizens that are guaranteed by the U.S. Constitution. The following are some of the more interesting technologies revealed in this budget request document from DHS.
