So how reckless do you have to be to count as reckless? If Al had been paying attention to what he was doing, none of this would have happened.
Maybe it would; that depends on just how suddenly Fred moved, and how observant Al is.
The most you could get out of this case would be a civil judgement for medical expenses/pain and suffering, but as a rule juries are reluctant to grant judgements to people who’ve already reacted by committing a greater injury (clean hands doctrine).
You have to be doing something (the jury would believe that) you should know could result in the injury of another person, performing the action in spite of that knowledge. If the prosecutor can convince the jury that any sane person would know that reaching to order without looking could break someone’s nose, then it’s reckless. If the prosecutor can’t, it’s not. Most likely couldn’t sell the jury on this one though.
