I'm not so sure it is too long. They need to have it detailed and spelled out to them. Even if they don't read it, it could be said they were served. If there did turn out to be some kind of higher being who administers justice, they won't be able to claim ignorance.
I was told I was supposed to read all their overly long shit for decades; hell, they can read this.
There's some good info in this letter; I'm saving it for my personal records.
