This is a thoroughly unsatisfactory outcome so far.
Normally it is the Crown Prosecution Service make this decision based upon the strength of the evidence to achieve a guilty outcome.
Does that suggest the police service had not carried out procedures correctly?
Or was it simply that the subsequent blood test did not exceed the appropriate limits.
I just think the public need to know.
I am aware that FlyBe are still considering the evidence; how long do they need?
