Whenever I see someone post like the op about how a jury doing something and claiming the jury has undermined their confidence by say finding someone guilty/not guilty I always tend to wonder who that person would think if the Jury had done the same thing but in a way they agreed with.
There is a reason it's a jury of "our peers" and not just judges/politicians or a computer spreadsheet, as it means that it's normal people making the decision of guilt rather than blindly following the law as written when they feel it is wrong in that instance. Think of the saying aboug "better to be judged by 12 than carried by 6", or that it is almost impossible to get a conviction for killing someone who has broken into your property almost regardless of the level of force you have used (you practically have to torture the person to death, or hunt them down in the street).
The magistrates or Judges also have a similar ability with an "absolute discharge" IIRC (I might have the wrong term), where they acknowledge that the defendant broke the law as written but feel that the circumstances were such that blindly following the law would have broken the spirit of it and so no punishment is suitable, possibly the best example of that would be say someone speeding to get an injured person to a hospital* or (and this is a rough example I read from an actual magistrate), back before mobile phones a husband and wife went camping well away from the nearest residence, both had drinks, the husband had a heart attack later that night and the wife, being miles from anywhere and no phones drove her husband to the nearest hospital. The law as written gives no defence to drink driving (if you're over the limit that's it), but the court considered that there had been no intent to drive when they drank, that it was a literal matter of life and death and that the wife was never likely to do it again (they also concluded that whilst the wife could have stopped sooner and called an ambulance, it wasn't reasonable to expect someone to do so under the circumstances).
*Or the tales about police pulling over speeding motorists and taking the occupants to the hospital when it turns out the passenger is giving birth, rather than giving them a speeding ticket as the law would normally suggest.
