The Brits are increasing the size of MI5, their domestic intelligence/security service by 50%:

They're adding 1,000 people. So yeah, it was at 2,000 before.
Or basically the size of my old High School. With the added people, it'll be about the size of two semesters worth of Chemistry 1A at Berkeley.
For reference:
"As of January 31, 2002, the FBI had approximately 11,000 Special Agents and 16,000 Professional Support Personnel."
(This taken from: http://www.fbi.gov/aboutus/faqs/faqsone.htm )
Current US population: About 290 million.
Current UK population: About 60 million.
So they're doing just fine. Still cute, though. I'm guessing the US has rather more law enforcement per capita overall (but I haven't actually checked on that).
...and, of course, I'm leaving out the Border Patrol, ATF, DEA and all Homeland Security folks who might or might not become involved in US domestic surveillance and security.
