When Harris interviews David Robert Jones during the absence of all the other agents, he is genuinely upset about Jones unwillingness to cooperate. As revealed later, Harris works for Jones.

Mr. Kohl says "The best we can hope for is life". Lifelong imprisonment is the maximum penalty in Germany. The death penalty does not exist anymore since 1949.
