There's a current list of suspicious words and phrases available from DHS! It starts on Page 24 of the linked report:

Privacy Impact Assessment for the Publicly Available Social Media Monitoring and
Situational Awareness Initiative Update

It seems I still cannot speak about clouds of pork without attracting the government's interest.

I'm surprised Flyertalk is not on the list of sites to be monitored, as often as people here speak of airports, airplanes, delays, cancelled flights, body scanners, transportation security, borders, screening, etc. We don't say much about SWAT teams, anthrax, agro terror, and drug cartels, but we've got those flight-related words covered.

"Electric" is on the list? Government resources are being expended because someone might say "electric" on the Internet? How can DHS possibly get any useful information out of this initiative?

And while I'm ranting, whatever does "establish a common operating picture" mean? DHS repeats and repeats it in their report, but it seems like a meaningless phrase to me.
