Mother of a son who has a felony on his record

It’s been almost 7 years since my son has been charged with a simple assault. He beat up the guy who tried to rape his sister. Yet, he is the one charged and not that dirtbag. He is almost 25 and still lives with me since the only work that will hire him is fast food. You cannot make a living with minimum wage. A grown man working with teens is very demeaning.
