Its an awesome book, in fact its the only book i read cover to cover in a few years. If you are deep enough into the hobby to be reading this post you will love to book.
As for dealing with "said people" its a moral issue. For me serving time means nothing. If a child molester serves his time, good, but Im not going out of my way to lend him a hand or invite him to my childs birthday party. If a 28 year old man applies for a job at my business and I do a criminal history check and see he has a conviction of possession of marijuana as a teen I could care less. Decide for yourself how you feel about someone who has been found guilty of crime X, make you decision about it and do what you feel is right.
