Wrong. One of the principles of logic is law of contradiction ie provable negative.
It is possible to prove a negative false.
My car is not red If I go out side and see it is red I proved it false.
It is also possible to prove a negation true.
My car is not red... If I go outside and see my car and it is blue. I have proved not red to be true.
You can prove a negative true using deductive logic. Using the law of excluded middle. When a and b are known.
Using inductive logic it cannot be proven as inductive logic only works on how probable something is.
If you cannot prove that someone committed a crime, they walk
Not true it is only beyond a reasonable doubt, because courts can only use forensic evidence, therefore they can only use inductive logic to make a conclusion.
If all the jurors saw her commit the crime then they and only they could use deductive logic to say she did it but still could not prove it to the court.
You can't prove a negative. Not true? It is called false. And yes you can.
You can't prove a negative true ?
Is a logical fallacy, and violates the law of non contradiction. And simply can't exist in the real world. It can't be true and false at the same time.
The statement claims it is impossible (can't) and possible (can prove) at the same time.
