Dear friends and Teachers,
- A police officer who is sent to a criminal gang to find evidence to prove them guilty is called a "insider policer" or "insider"?
Thanks a million!
I haven't heard of those."insider policer" or "insider"?
not a teacher
Undercover (police) officer
Someone on the inside
There was a bank robbery and police believe it was a inside job. - Someone from the bank personnel was involved.
Also, 'insider trading' in stock market which is illegal.
'Insider' cannot be applied in this context.
