I suspect it stands for Marijuana since he is in a “support club”.

Being in a support club does not mean that one consumes or engages in the commerce of marijuana. One has nothing to do with the other.

I take the bikers “side” in this in that feds and or cops screwed up and did almost all of the shooting.

It wasn't necessarily a screwup, and yes the police did almost all of the shooting and the killing and wounding.

But Bergman is a huge dumbarse, plenty old enough to know better then wear a Bandido wannabee patch.

So he deserved to be arrested, fired, out of thousands and thousands of dollars, injured and his family devastated because you don't like his protected expression of speech? I don't.

Freedom of association is a big one in this country, buddy.

I found this and it makes more sense

The Diamond patch with “1%” or “13” worn with the 3pc back patch signifies the club is a 1% or 1% support club.
