Ok quiet down I answered your question. Pre trial motions address questions of unfair trial due to venue. Case closed.
Let me help you one more time as your struggle with the unfocused mind.
My question was: Did the defense ask for a change of venue?
Your rambling about voir dire and pretrial motions and jury nullification did not answer the question of whether a change of venue was requested. The fact that it would have been addressed in a pretrial motion does not in and of itself confirm that that or any other request was made, only that that is when it would have been addressed. But no, you have the marbles you want to roll out on to the table hoping that what you want to see contains an answer in there somewhere.
The answer to my question- based on my own search- is: YES. A change of venue was requested. Your view on it or when it was handled in the process and whether it would be jury nullification if granted, so on and so forth are neither here nor there. The answer is YES.
Try to process that: Yes. That is a complete answer.
