If people are that careless they should not be anywhere near electrical work or EICRs.
When other possibilities are eliminated, all that remains is the truth.
Exactly, they should not.
If those are the only two alternatives and no other is possible, then in my mind, exactly as you said.
Both options render them as unfit for purpose.
Reminds me of something a few years back, "Women Empowering Women" or something like that as it was known at the time.
One women made a lot of money and passed her friends into what was not unlike the age old "Chain Letter" scenario.
I think she was a teacher or something.
Some argued she was devious and should have known that those very few higher up made money whilst a very lot of the rest of them lost money.
She and a few supporters claimed she did not know.
It was mentioned she should lose her job for it along with anything else.
Some argued that she couldn`t because she might be "innocent".
I mentioned that no we could not be absolutely certain of guilt or naivety but we could be certain that it was one or the other and both rendered her as unfit to be in her job.
Whether what I mentioned was actually considered is another story though.
This case is similar - should not be trusted, whichever of those two option applies.
