Judge Matsch's ruling, which relied heavily on the community victimization issue, is well worth reading. (Also see my post on this here.) The same thing has happened in Boston. The Government in Tsarnaev's case has even claimed that everyone in Boston is a victim. If so, how can anyone from Boston sit as a fair and impartial juror? Judge Matsch wrote:

...Because the penalty of death is by its very nature different from all other punishments in that it is final and irrevocable, the issue of prejudice raised by the present motions must include consideration of whether there is a showing of a predilection toward that penalty.

...Upon all of the evidence presented, this court finds and concludes that there is so great a prejudice against these two defendants in the State of Oklahoma that they cannot obtain a fair and impartial trial at any place fixed by law for holding court in that state. The court also finds and concludes that an appropriate alternative venue is in the District of Colorad
