How had Mr Radley seen to it thay his younger son arthur caused no further trouble in Maycomb in to killl a mockingbird?

I red this book last year in my English class (being a freshman in high school).

Arthur Boo Radley, I believe, was the son.

Everyone thought he was a murderer or a pedophile. He was neither.

Boo Radley was a quiet man. He never left his house and when he did people, after awhile, realized he was a sin-less man. He was as kind as nature on a spring day. Arthur Boo Radley was a good man. He spend the rest of his time, just like his past, in his home. He didn't like being outside in the light after so many years.
