In case any force is considering going further down the non-destructive Method of Entry route, we at Devon and Cornwall recently sent 3 instructors on a 3-day Locksmith Course run by MPL in Bradford (http://www.mpl-locksmith-training.co.uk/). Highly recommended it has transformed the way we use Snappers, Pullers and Mica Cards together with opening up new avenues of drilling & picking (you never know!).
The course was very bespoke and the instructor more than happy to adapt to our needs. If you want any more info, feel free to contact me.
