with a drug overdose the doctor just gives narcan to the patient and he issues a medical report that a person was in danger of life probably because a drug overdose.
then nothing happens because in italy personal use of drugs is not a crime.
it is a crime to sell drug to other people or to keep drug in such a quantity it cannot be considered for personal use.
so the police will receive the medical report and nobody will care about it.
very often doctors do not issue reports to the police in such cases because these reports are useless. but in theory , doctor on duty in the public hospital ( the only ones really treating emergencies) have to issue medical reports for attending patients in danger of life because of violence....
doping is a crime, so it is different.
ricco is popular, so it is different.
police and judges like to investigate on popular people, because that draws attention from the media.
if there was an unknown criterium amateur racer instead of ricco' in the emergency ward of pavullo hospital, probably things will have gone differently.
nobody at the police would have been excited by the medical report eventually issued by the doctor on duty.
anyway , in the ricco case, the doctor did not break any law , since he was working in the nhs and issued a report to the police. at the opposite, if he did not make the report, he could face a prosecution.
obviously things are different if the doctors calls the media to detail what it is happening in the ward.
i hope it is clear, because my english is not very good, but i like to write in this forum
