Sodomy II: “A sackable offence,” says witness

More revealing testimony from the Sodomy II trial today.
Excerpt from a Malaysian Insider report:

Both containers (containing DNA) bore labels that were dated June 26, 2008.
Anwar is charged with sodomising former aide Mohd Saiful Bukhari Azlan in a Damansara Heights condominium on the same date.
The court has been told the complainant was swabbed for test samples of his DNA only after seeing doctors two days later, on June 28, 2008.
Dr McDonald, who was briefed of the history of the case, said such a labelling meant one of two things, either the samples were indeed taken on June 28, 2008; or the samples were labelled wrongly.
“This is a sackable offence,” he testified.
“You could kill someone. If you change something on a medical result, you could kill someone,” he said.
Dr McDonald explained that the proper thing to do would be to verify with the source if there has been a mistake and move quickly to correct it and have those steps recorded.
