There is a very different level of proof required in criminal and civil court.
If a jury actually does what they are supposed to then the same exact jury could find someone not guilty in one, but at fault in another.
A "preponderance of evidence" means someone is more likely than not to have done something based on the evidence. So if there is a 51% chance they did what they are accused of, then they can lose.
However
"beyond a reasonable doubt" means even if you feel they are most likely guilty, if there is a decent chance they are not you are supposed to find them not guilty.
This means even if you believe they did it, but there is say a 20% chance it was someone else, you are supposed to find them not guilty even though you are 80% sure they did it.
This is under the premise that it is better for a guilty man to go free than an innocent man put in prison.
Now many potential jurors may not do this, and instead base their decision on what they feel most likely occurred, but they are not supposed to, and are removing some of the accused rights by doing so.
(In many nations it is the reverse concept. Where if the person was arrested for a criminal action, and are believed most likely guilty by the jury (or just judge or judges in some), then it is best for society that the criminal be found guilty.
Some of those nations go even further and start with the premise that if the government went through the trouble to make a case, then the person must be assumed guilty and will be found guilty, unless they can clearly show otherwise.
Meaning if there is any doubt to their innocence they are to be found guilty.)
What all this means is if jurors are doing what they are supposed to in respecting the rights of the citizen, it would be quite easy to find someone not guilty in a criminal case where it may have been self defense, but still find them most likely to have acted poorly in a civil case.
We don't know all the facts in the trial so lets make some assumptions from what we have:
So lets say this guy shot his wife, and the details show he may not have needed to. That he in fact was angry over his wife sleeping with the other man and not really there just to take pictures.
But lets also say that his wife perhaps acting in self defense or angry herself tried to flee or use her car to leave her dangerous husband who was clearly following her.
That he was blocking her path, and so she tried to go around him or even through him.
Lets say as she went passed him he shot through the side of the car door, hitting her in the leg.
So we have both a potentially dangerous guy that may have followed her for reasons other than just taking pictures, and a guy who may or may not have actually needed to use his gun to defend himself.
In a criminal trial we are supposed to give him the benefit of the doubt. He may have gone there, put himself in that situation, confronted his wife, argued with her, etc
She may have also actually tried to run him over, perhaps doing circles or was turning around to hit him again, or he may have believed she was trying to do so.
So he may have been completely in the wrong, or he may have been acting in self defense. So we have reasonable doubt that he is guilty.
In civil court however he clearly put himself in that situation, chose to confront her, chose to create a scene in public, and then shot someone as the situation escalated for whatever reason.
We may have reasonable doubt he was criminal in the shooting, but we can certainly assign a significant level of blame to him for the situation and the result. The level of fault turns into $$$$.
How at fault can also be split amongst the parties. Lets say she was uninsured and required $80,000 in medical care, physical rehabilitation to walk again, and psychiatric treatment to get over the emotional trauma.
If he was 50% at fault and she was 50% at fault, then he would owe her $40,000.
Thankfully, in Florida the Civil case would not be permitted to proceed.
Florida on the other hand essentially tells the jury that it must decide everything at the criminal trial. That could actually be worse for a shooter.
If you are a jury member and you feel that the guy is 51-90% likely to be guilty, but have some reasonable doubt, you may still find him guilty so his "victim" has some recourse rather than letting him off scot-free.
If a guy put himself into a situation likely to create a need for force and then played a big role in escalating the situation, it might be fair that he pay the person shot or their family something for his poor decision making.
But in Florida you cannot both do that and give him no criminal record or prison time in a separate civil and criminal case.
You have to find him guilty of criminal charges to hold him accountable for any wrong doing.
So someone in Florida may actually be more likely to go to prison or get a felony record if the jury has any sympathy for the person shot or their family than if criminal and civil were separate. It is all or nothing. So I see a higher probability of finding people guilty (or guilty of one of the lesser crimes charged) who are charged for potential self defense shootings, and then giving a low sentence as the balance if they really think it may have been self defense.
