From the radio news “…a man who is holding his wife hostage after shooting a policeman earlier in the day is sitting on the couch wathcing television. He appears to be quite rational.”
Okay – he’s shot a policeman already, he has his wife hostage, the seige has been going nine hours, he his surrounded by battalions of armed police and he’s sitting there watching television. Rational is not the word that would spring to my mind.
