limit it to people you have personally known and trusted for many
years because then it would be too small to be effective. You need to
use something called the ring of trust. If I trust A and A trusts B
then I should trust B. So if Hermione made an error it's that she
trusted Cho."

Del replies:
I have two objections.

1. Underground resistance movements are very often either small, or
cut up into small cells, precisely because of the risk that one single
person could betray a large chunk of the organisation.

2. I always go back to the problem of the way the DA were first
advertised : it wasn't about building an underground anti-Umbridge
resistance movement, it was only about learning some practical DADA.
In other words, it's one thing to ask A "Do you think B is really
interested in learning DADA?", and another thing entirely to ask them
"Do you think B can be trusted to keep an underground anti-Umbridge
resistance movement secret?".
