Though jurors are usually chosen from the area where a crime was committed, sometimes a trial is moved to a different location. This is called a change of venue. Why might a judge grant a defendant a change of venue?

If a crime is well-publicized with extensive news coverage, it may be difficult to find an impartial jury. The people you would be choosing jurors from would have already heard a lot of details on the case, and might have already decided the defendant is guilty without knowing all the facts.

Explanation:

In high-profile matters, a change of venue may occur to move a jury trial away from a location where a fair and impartial jury may not be possible due to widespread publicity about a crime and its defendant(s) to another community in order to obtain jurors who can be more objective in their duties.
