What immediately springs to mind when I say “Emerald Prism” and “Crossley Star”?
Some new age mumbo jumbo? Crystals? Well-being bracelets, etc?
David Icke?
Nope.
The Emergency Planning Officer for Hampshire Police in the UK, Greg Snelgrove,

gives a running commentary via his Twitter account:-

regarding his attendance at various terrorism, critical national infrastructure and Olympics security related training exercises.
Sometimes these are just classroom based desktop sessions but others involve, for example, simulated fuel depot disasters at real locations with real equipment.
One of the gems from Greg’s broadcasts includes Exercise Crossley Star at the Health Protection Agency’s Porton Down laboratories. On the same campus is the former chemical weapons establishment and now research centre for bioterrorism countermeasures.

What about Exercise Emerald Prism? The response to an extended hostage/siege scenario – held at RAF Lyneham.

Presumably the 22 SAS’s finest were in attendance. Did they all tweet too? Well no, they’d write a book. But I digress.
Perhaps the most controversial of Greg’s Tweets is one that was deleted soon after posting:-
The same Exercise Emerald Prism, but at SECTU – the South East Counter Terrorism Unit.

The exercise code names, locations and descriptions were not in the public domain before Greg’s announcements. The only mentions across the whole internet were on his Twitter account (and later, assorted aggregators which picked them up).
Thames Valley Police and MI5 can be thankful that chatterbox Greg didn’t actually state the location of his day trip to this extremely sensitive operational facility.
Or else he would have to rely on his fees from his part time work as a Prince William “celebrity look-a-like”.
