There are some cities that don't have an alert mark. (/sarc)
Some incidents are pure FUD - nothing to do with Terrorism:
[WFSB] CONNECTICUT -Hospital Flooded With Stomach Virus
"Doctors at the hospital said the virus, which has yet to be identified, seems to be spreading through the community"
I hardly see why this 'incident' belongs on a "Global Display of Terrorism and other suspicipious activities"
So some folk in CT have $hit themselves.... Sorry - someone getting 'racing stripes' in their skivvies is not suspicious to me...
