... but they are not driven (too often) by hordes of lawyers ...
The Euro-centric approach to terrs (violent non-state actors) is very much driven by law-lawyers (whether in hordes[*] is perceptional) - e.g., the Eminent Jurists Report and a number of UK policy papers cited by David in War Crimes. The approach is purely a law enforcement and intelligence approach.

Possibly, that has made some Euro agencies more keen on developing the facts before events go down - and sharpening both intelligence and counter-intelligence skills - because of what in effect are tougher legal standards.

Personally, I would not give up our dual track system (FBI-DoJ and DoD; and perhaps some more alphabet soup for special missions); but one has to realize they are separate tracks - different rules and cultures.
