...However, you forget that jury selection is not just by chance. The jury pool is by chance, but the judge and/or attorneys can challenge the selection of the jurors. This is where the unfairness comes in. The judge and/or attorneys approved of the jurors before the trial. Dylan's attorneys should have challenged.
The district attorneys and the defendant's attorney(s) cannot challenge the selection of jurors like it's a board game. Both sides can question the jurors of usually about 30-40 people before the final 12 (actually in Ramsey County, MN, 13 total, just in case someone gets ill or can't continue) are paneled.
The sides choose jurors like it's a pick-up basketball game. After public questioning, both sides submit their lists to the judge and they have their equal turn at selecting jurors. The actual juror selection challenging is limited and has to be approved by the judge. Attorney's cannot start asking for a new turn or whine like it's a game of Monopoly. In fact, challenges don't happen all that often because in the world of judicial law, challenging another attorney's selection is like telling your co-worker how to do their job - it had better be a damn good reason or every attorney in the county will despise you.
The only times attorneys really challenge juror selection is like, for example, defendant side questions a juror about his family history and knows that his family has been arrested a lot and hates cops, and they choose him. Then the prosecution side could challenge to the judge that defendant attorneys are selecting that jury because he/she has a bias towards law enforcement. But here's the thing: attorneys and judges aren't stupid. If they see anyone talking dumb, even if that person will help their case, they won't touch them.
I think you watch these law movies about racism and you believes that's how real-life court is. You're convinced that Jasper, Earl, Trevor, Bobby Jo, Buddy Lee, Harley, and Gator, all cousins and brothers at the same time, are coming to a jury bench near you today. Get to reality, dude. We all know everyone has bias but this isn't 1800s railroad building times anymore.
Your thinking is flawed because if you believe that the prosecution side will choose 6 jurors who hate non-whites, then wouldn't you also believe that the defendant side will nullify that by selecting 6 immigrant-loving, Christian-hating, America-hating liberal yuppies? Mind you, this is just for example. As I have said, attorneys and judges aren't dumb and will not allow a court room to turn into race wars made for television.
You only see one side. You are truly bias. You only see the prosecution side as the evil side and that they are bending the laws in order to have 12 jurors on their side.
