DHS needs to be shut down. The reason they need so much ammo is because DHS employees are incompetent. Take the TSA for example. The TSA is only competent enough to abuse amputee Marines, old ladies in wheel chairs and children. I would feel much more confident in traveling if I was able to exercise my 2a rights on airplanes and other forms of public transportation.
We have given up our freedom and billions in tax dollars for less security. Most Americans are frickin' stupid wimps. If we only would abide by the constitution none of these problems would exist.
