What if it relies on specific personnel to actively purge the database? What if said personnel are poorly trained, low pay, exteme limited time, and simply does not care?
How likely does a TSA agent fall under all of those criteria? (Hint: very likely)
Edit: here’s the fucking clincher directly from their website
During periodic testing and development, TSA and DHS Office of Science and Technology (S&T) may retain passenger data for up to 24 months.
I am pretty sure I read somewhere that they plan to test this system for the next decade. So technically they don’t delete anything due to being a long as fuck period of “testing”.
