Why must one have a police interview exactly?
You areassuming that criminals come to teach English, not law-abiding people such as myself.
What has the police got to do with an innocent English teacher who has never committed any crimes.
This idea is propogating spy networks. Do you know how horrible it is when you are innocent to have spys continuously looking over your shoulders watching your emails, asking who you are meeting in the weekend, etc. They are luckly such teachers are here, living under these conditions.
I really think you oughta re-think why one must have a police interview.
