I've noticed online that some are describing this traitor/idiot as a "whistleblower". I hope he spends a very long time behind bars.
To spell out why this description is nonsense:
A "whistleblower" is a person inside of an organization who learns of criminal or ethical misconduct within said organization, and alerts the proper public agencies (law enforcement, IRS...), or the proper agencies within the organization (auditors, supervisory board...), or, failing that, the public (via the press, public data dumps...) with a view to rectify the misconduct.
This Teixeira dude was an insider alright, but ...
a) ...the documents he hauled were not focused on documenting any misconduct, they seem to have been on a number of issues including lots of perfectly legitimate intelligence assessments.
b) ...he did not alert any proper agency, nor the public or the press; instead he kept it all inside a tiny group of young gamers. For bragging rights or whatever
c) ...he did not have a plausible, viable goal, let alone plan, to put an end to any misconduct
So there simply was no whistleblowing.
