Ernst Jürgen: We Germans are experts at forgetting. We forgot we were Nazis. Now we have forgotten 40 years of Communism - all gone.
Ernst Jürgen: In the Stasi, we had a basic principle: ask enough questions and a man who is lying will eventually change his story. But the man who tells the truth cannot change his, however unlikely his story sounds.
Dr. Martin Harris: They had me convinced that I was crazy. But when they came to take me, I knew.
Dr. Martin Harris: I didn't forget everything. I remember how to kill you, asshole.
Dr. Martin Harris: Do you know what it feels like to become insane? It's a war between being told who you are and knowing who you are... Which do you think wins?
Rodney Cole: There is no Martin Harris. He doesn't exist.
Answer: Because the killers need to make Liam Neeson's death look accidental. The police think Neeson is crazy, and is not telling the truth when he claims Liz is his wife. The police simply think that Neeson is mentally ill and so dismiss his stories and allegations as untrue. However, if Neeson is then found murdered, there is the possibility that the police think Neeson might have been telling the truth, investigate, and foil the villains' plot. Therefore, Neeson must be killed to stop him investigating - but he must he killed inauspiciously, so it looks like an accident, so as not to make the police suspicious. Thus the poison in hospital - hopefully it would be put down as a standard non suspicious hospital death. And the drugs in the car park at the end of the film are deliberately mentioned by Professor Rodney Cole as being essential in making Neeson's death look an accident. Cole says that Neeson will seem to have killed himself with heroin and so will not consider his death suspicious. So basically these elaborate ways of killing are in order to make Neeson's murder seem an accident and so not make the police investigate.
