"As for targeting innocents or citizens, I have faith that any investigations done on people-either citizens or foreign- will be done according to the book."
Since the border patrol has decided to change their procedures so the incident will not happen again, it appears that if they were initially following the "book", it has been re-written to give more protection to our citizens.
Trust, but verify - hard to do when no one tells you what's in the "book".
Maybe I didn't make myself clear. I'm not going to debate this subject.
That said, I distinctly remember reading the Customs and Border site about a year ago (a good idea for I travel often out of CONUS). It made pretty clear (and I paraphrase here) that they reserved the right to detain and search anyone they might have doubts about or have reason to suspect. They busted some good naturalized citizens here in CT last year. Seems they weren't entirely truthful about who they really were. Unfortunately, we have a few native born citizens that seem to have gone to the dark side as well.
99.9999% percent of people cross the borders with little or no problem. The rest get checked, period.
