Indeed Sir! Post 4 is clear to me and others also, no doubt.
However, the evidence suggests it was not so clear to the OP. You gave him the choice between 'a ticking-off' and 'a legal caution', and he picked the latter. However, this caution was given before interview; and the magic words for interview under caution might well be described as a 'legal caution', and are certainly not anything like a ticking-off.
Just a benign observation - probably resulting from my just having done an afternoon's teaching thing for undergraduates and therefore being excessively evidence-based and analytical.
