EDIT: Actually the incidents in the article are fairly tame. There are much more egregious examples.
Someone made an error. They corrected themselves. iow, nothing happened.
Also, the "error" is particularly egregious and Stasi-like: collect info on people doing something legal, nay, constitutionally protected. It's also very typical for US Secret Police to do. The COINTELPRO program infiltrated Quaker organizations in the 60s, some DoD office did it before Gulf War I, and someone seems to be trying it today: http://www.afsc.org/ht/display/ContentDetails/i/5264/pid/268
I suspect the Secret Police tries to infiltrate Quaker organizations because it's so easy: they welcome just about anyone, and do all their work out in public, unlike less trustworthy organizations like the DHS and TSA.
