25mph in 20mph zone. Homerton E9

Before I fill out "Request for Driver's Details," I wanted to ask your opinion. Is there anything in the photograph, calibration certificate, or anywhere else that I could use in defence? Thank you in advance.

Well you have to name the driver regardless, so even if you want to look for possible defences for the driver, no need/point delaying the reply.

But no, I see nothing of use there.

Okay, I appreciate your opinion. Thank you.
