Question: I am quite amazed by the verdict from the jury on Philando Castile's case where the cop was acquitted of any charges despite the graphic [video evidence](https://www.youtube.com/watch?v=85Y_yOm9IhA). 

**Question:** Are jury selected from the same community the crime is committed (in random) or they are based on educational merit. With the evidence presented it was more statistically probable that either jury would not reach a conclusion or will verdict will lead to conviction.

Insofar as Minneapolis is in Hennepin County, residents of Minneapolis would not be called as jurors, but any resident of Ramsey County could be.
The jury is selected (semi-randomly\*) from members of "the state and district where the crime shall have been committed", per the Sixth Admendment; as a practical matter, they are pulled from the prosecuting county\*\*.

\*The initial selection is done at random; however, lawyers from both sides will eliminate prospective jurors , in a process known as "voir dire" or "jury selection", to eliminate biased jurors.

\*\*In certain cases, the defense can move to change the location that the trial is held and/or the jury is selected from, if they have evidence that the jury pool has been "tainted" against them.
