The better you are as a soldier, the worse you are as a human being. - Harry Harrison

Without being too clinical, let’s say his brain was affected.

When the office door opened suddenly I knew the game was up. It had been a money-maker — but it was all over. As the cop walked in I sat back in the chair and put on a happy grin. He had the same sombre expression and heavy foot that they all have — and the same lack of humour. I almost knew to the word what he was going to say before he uttered a syllable. "James Bolivar diGriz I arrest you on the charge—" I was waiting for the word charge, I thought it made a nice touch that way. As he said it I pressed the button that set off the charge of black powder in the ceiling, the crossbeam buckled and the three-ton safe dropped through right on the top of the cop's head. He squashed very nicely, thank you. The cloud of plaster dust settled and all I could see of him was one hand, slightly crumpled. It twitched a bit and the index finger pointed at me accusingly. His voice was a little muffled by the safe and sounded a bit annoyed. In fact he repeated himself a bit. "On the charge of illegal entry, theft, forgery—" He ran on like that for quite a while, it was an impressive list but I had heard it all before. I didn't let it interfere with my stuffing all the money from the desk drawers into my suitcase. The list ended with a new charge and I would swear on a stack of thousand credit notes that high that there was a hurt tone in his voice. "In addition the charge of assaulting a police robot will be added to your record."

The human race is gregarious, I knew that even though I had been denying it for years. I was going to keep on doing the loneliest job in the universe — only I wasn't going to be doing it alone.
