I know a report about this came out last month.
From that same article, DHS has also "unclassified" this type of "target" in a much broader sense to include "patriots" as of 2009.
This has been going on for some time, and it's also similar to the memo's that were passed out last year to law enforcement agencies, regarding certain types of bumper stickers and U.S. flags on vehicles.
Regardless of whether it's old news or not, it's still a very important topic - even if someone re-posts it 6-12 months later this year. I for one, will always +1 this topic.
Then again, it may be due to something else entirely.
