Given that the limit for pilots is virtually zero, some may wonder how the person who saw fit to report him could genuinely have suspected he was over the limit.
Is it not the case that, irrespective of how the police were informed of a
possible offense being committed, that the officer may only administer a breath test if
he has grounds for believing that the person has been drinking? I.E. he could smell Alcohol on the pilots breath/saw him/her drinking an alcoholic drink.
If the police did a breath test just based on a third party's say so would that not have been illegal?
