Well of course there are or this would be an absolute and there is no such thing.

Farrakhan recruits most of his members from prisons.

If you are alone, you have no protection.
If you are with a group, that guarantees you some protection.
The recruiting Farrakhan does in prison is a topic for a whole other thread—and more.
