应该是进行精神评估(psychiatric evaluation)，而不是心理评估(psychological evaluation)。
心理评估每人都需要，但精神评估就不是这样的了。遇到专业知识，应该向有关人员请教，而不是为翻译而翻译。
MONTREAL - The lawyer for alleged body-parts killer Luka Magnotta could ask for a psychiatric evaluation Tuesday for his infamous client in the gruesome dismemberment and murder of Jun Lin.
Magnotta, 29, pleaded not guilty Tuesday to charges including first-degree murder, indignity to a corpse and criminal harassment of Prime Minister Stephen Harper.
The slightly built former porn actor stared blankly into the camera as he entered the plea by video-conference from a booking centre where detectives had interrogated him in the morning.
At the courthouse, the judge, Crown, defence and about 100 spectators and journalists watched Magnotta on video screens in a courtroom and overflow room.
