DHS has released its new "northern border strategy" -- find it here.
I don't have time to read through the whole thing and analyze it now, but here are a couple of interesting finds that strike me as relevant right off the bat:
"DHS has deployed additional technology to the northern border, including thermal camera systems, Mobile Surveillance Systems, two Unmanned Aircraft Systems (UAS) and an accompanying Operations Center, new national distress and command and control networks...and Remote Video Surveillance Systems." (p. 4)
"CBP deployed next generation Radio Frequency Identification (RFID) technology and next-generation license plate readers covering nearly 100 percent of land border traffic as of June 1, 2009." (p. 17)
"We will share information and intelligence among our domestic and Canadian partners in real-time and in a manner that respects civil rights and civil liberties and in compliance with privacy law and policy." (p. 8)
