The DHS is doing multiple things here 1) Tracking everyone who posts links to the site and creating a massive database of gun owners (with your comments on the matter). 2) Creating distrust of the government with the obvious misuse of taxpayer funds to buy ammunition not used for law enforcement.
Link analysis software can be used to cross reference database entries like the one created by team Obama in the last election (and openly praised via various news outlets). Big data is here and they can record everything you google or post on Facebook. Storage is cheap and the software exists to keep everything you post for more than six months.
Right.
But keeping quiet does not protect you because the ultimate end of all of this monitoring will be to monitor what you read.
Like reading Glenn Beck or Rush Limbaugh will put bad marks by your name.
Reading the daily kos will put a gold star beside your name.
I have been saying that for a while. That said, good luck implementing any seizure activity en masse before the common man finds out and either rebels or hides his assets. Just based on numerical data they cannot perform any seizure that can be completed in a timely manner.
