Conviction variance

Sometimes the justice system actually can't know whether somebody's guilty or not, but because a serious case has been brought up, they have to decide something.
I think there are variances of convictions:
Guilty,
Not guilty,
Safe boundaries.

When a murder has happened, there's an instance when it's not safe to let someone loose into the society even though he/she might not be the murderer. There's substantial prove even though not at 100% mathematical/quantum certainty that he / she was the murderer, to not let this guy loose.
I think in this instance the law should be able to suspend him/her from common societies for the sake of safety. But I think it's wrong for the law to convict this person guilty.
For example there were lots of witnesses saying that this guy was at a place during the night. But there were also some who said that the person was at another place.
Well it was night and some people looks the same when he/she was drunk and/or using similar make ups.
So even though there were no lawyers to present the case, judges who are rational could consider this possibility and should be undeterminant because it's just right to do so.

Now, I have an idea, why not point based, alternative voting system? One that gets rank one score 7 points, one that score number 2 get 6 points, etc?

More reason why do we have to be good?

The scarcity of the world is not of time nor energy but of mutual solutions.
We see that protection to intellectual property could lead to some more inventions, even when some might argue that current form of IP law hindered some other types of potentials but, I would say that respecting and giving thanks to the source of our mutual solutions is a crucial part of progress.

Giving thanks to sources of solutions, like planting back the forest, and not bombing the coral reefs, is the only logical thing to do.

Therefore it's not about how much sacrifice you made when creating a solution but how useful your solutions are.

Therefore little things that people do actually are very valuable beyond imagination. The fact that people held themselves from doing criminal activities like stealing, hurting other people, and rioting... the fact that people participate in the law and also good mutual values in the society. Shows that we also have to give thanks to these non-practicioners of evil and practitioners of good.

But if we were to do that, wouldn't it mean that we're to loose most of our money to these people?
Certainly yes.
But since we are also people who often or maybe for some of you always do good for people, then you too deserve thanks from the society I think.
Therefore if you do evil lifestyle, I think you owe to the mutual solutions you enjoy right now, like orderliness, peace, kindness, good prejudices, helpfulness, public facilities, public knowledge, etc... and I'm telling you and reminding myself... these are very, very, very, very, very... expensive.
