Time Criminals

"'The alien corn... Ruth in exile... It's in the Bible.'"

-Poul Anderson, "My Object All Sublime" IN Anderson, The Collected Short Works Of Poul Anderson, Volume 2: The Queen Of Air And Darkness (NESFA, Framingham, MA, 2009), pp. 337-343 AT p. 342.

- Another Biblical reference.

We know how time criminals are dealt with in three fictional timelines. 

(i) The Time Patrol runs an exile planet.

(ii) "...a general court-martial will exile you for a year in a nasty period, say 1974 with its strict rationing and forced labour."

-Robert Heinlein, "'- All You Zombies -'" IN Heinlein, The Unpleasant Profession Of Jonathan Hoag (London, 19800, pp. 126-137 AT p. 134.

(iii) "'...they do send their very worst criminals back into the past.'"

-"My Object All Sublime," p. 340.

"'When and where were you left?'

"...Near Warsaw, in August, 1939.'"

-ibid., p. 342.

"I left him in Damascus, the year before Tamerlane sacked it."

-ibid., p. 343.

In any case, if you put someone far enough in the past, then he is dead by now.
