Was the Arbery trial fair?

Why did the court rule out all this? What is it with this Judge?

"However, there were five key arguments the court ruled could not be presented to the 12-juror panel who will decide the fate of the three white men charged
They included Arbery's mental health records and criminal history, and the fact that trace amounts of THC were found in his blood after his death
The judge also refused evidence claiming Arbery was known as 'The Jogger' because he would jog to convenience stores, and run out with stolen goods!".
Let alone that the video that shows Arbery trying to grab the gun from the defendant trying to question him? Didn't Kyle Rittenhouse fire on people trying to take his gun from him?
