CTE should not be used as an excuse for violent criminal behavior as many former players who suffered concussions did not commit violent crimes.

“there are so many NFL athletes that that never murdered anyone despite severe concussions”

“one thing I didn't know about CT before researching for this episode was that you can't be diagnosed with CTE while you're alive you can only be diagnosed with probable CTE”
