i know an expert witness. he got a degree in CS. worked for a year or two writing code. then has been considered an expert in the field and now flies around the country to various trials being an expert on modern development choices. the side that’s hiring him gives him a pdf with all the info. he basically memorizes it, repeats it while testifying, and gets paid absolutely bank cash. he’s been doing this almost 20 years. i think it’s legalized corruption in the justice system
