It’s far from mean to expose perjurer that’s escaped from trap (7)
I believe the answer is:
outlier
'it's far from mean to expose perjurer' is the definition.
I can't tell whether this defines the answer.
'escaped from trap' is the wordplay.
'escaped' becomes 'out' (I've seen this before).
'from trap' becomes 'lier' (I can't explain this - if you can you should believe this answer much more).
'out'+'lier'='OUTLIER'
'that's' acts as a link.
Can you help me to learn more?
(Other definitions for outlier that I've seen before include "Isolated data point" , "Extreme deviation from the mean - our tile (anag)" , "Something detached from the main grouping" , "Statistical anomaly" , "Suburbanite" .)
