Is there something to this? From the ABC affiliate in Denver ...

You could be on a secret government database or watch list for simply taking a picture on an airplane. Some federal air marshals say they're reporting your actions to meet a quota, even though some top officials deny it.

The air marshals, whose identities are being concealed, told 7NEWS that they're required to submit at least one report a month. If they don't, there's no raise, no bonus, no awards and no special assignments.

"Innocent passengers are being entered into an international intelligence database as suspicious persons, acting in a suspicious manner on an aircraft ... and they did nothing wrong," said one federal air marshal.

It would certainly be nice to see some other news outlets check into this.
