The diamond patch with "1%" worn on the front of a "cut" (vest)
with the three-piece back patch signifies the club is either a 1%
or 1% support club. They may not be the dominant club in the area
but will almost certainly be sanctioned by the local dominant.
There have been situations where the dominant is not a 1% club but
those are rare and, quite possibly, extinct. The number "13" is
also sometimes worn in a diamond patch. It is alleged to represent
the thirteenth letter of the alphabet, "M" which stands for
marijuana. Or maybe it's just a cool number. Rightly or wrongly,
law enforcement organizations (LEO) regard the diamond patch as an
outward, visible indicator of criminal activity within the
motorcycle riding community. While the best propaganda usually
contains some element of truth, the distortions are often so
outrageous that if they weren't oriented towards spreading fear,
they would be comical.
