" consent to mine your grocery receipts, your credit card purchases, and even your Facebook posts to determine if you are a terrorist risk – not just once but on an ongoing basis.."
" what you post on social media while you are enrolled in PreCheck – it is fair game"
" information collected by the agency’s private sector contractors could be used for other government or private purposes"
Some of this dates back at least as far as Napolitano's early days. IIRC, she wanted a points-based 'domestic extremism' index. More points, more scrutiny and/or restrictions. I suspect this idea is not dead and will likely be linked to a universally-required national ID if/when implemented.
IIRC, one of the suggestions that could get you 'points' (demerits) was ordering an airline special meal. Apparently that might include things like halal or even vegan meals. Unusual = suspicious, right?
Unsurprisingly, I do not recall any mention of easy, transparent ways for citizens to challenge false 'points' assigned to their record. Think how bad it is to correct a mistake on your credit record - now magnify that x100 and apply it to everything you do.
The apparent black mark US travellers are currently receiving for the crime of travelling to/through IST is an example of how similar information is already being used.
