Since CTE can’t actually be diagnosed without dissecting the brain you can’t really use it to absolve anybody or lock them up.
But thats exactly what this kind of piece is trying to do.
Look at the context this is talked about in the article
sympathetic angry docs
blaming another party for not doing enough, not the guy eho murders six people
this is all laying the groundwork for being able to label these people as not guilty due to a medical condition
I don’t think anyone is absolving him for the crime due to CTE. The sad part is apparently he was asking for help and never received it. Mental illness is real and often treatable. Sad and tough deal all the way around.
