The evidence arrives as a photograph of a ledger, taken at an angle, in poor light.
Hundreds of them, against tickets too small to justify a senior reader on any single one.
The real constraint
It is not that your officers cannot appraise. It is that the record is thin, the proof is a phone photograph of a handwritten book and a mobile money history, and there is no time to reconcile any of it by hand. So the parts that are hardest to read are the parts that end up assumed.
The ledger in the photograph
That photograph is the evidence, not a poor substitute for it, and it is read as the page it is.
The senior reader you do not have
That reading is beside the officer while the file is still open.
