It's actually a slanted SS Gestapo logo that many hard-core outlaw bikers wear along with the Iron Cross and Swastika.
It's getting late and I'm an old guy and getting tired, but still can't believe some are defending the 1%er's (outlaw) right to free expression/assembly. They should all go the way of the Mafia. Many do according to the History Channel. Some still want to ignore those under-cover agents busting the gawd-awful murderous bikers. Guess I should leave them in their mis-placed innocence.
After all, I'm an anti-1st Amendment person according to their twisted beliefs. Take care and thank you for recognizing who are the bad guys.
Hang in there..I have appreciated your first hand knowledge of 1%ers.
...like the tattoo on the left guys elbow and the patch on the right guys vest.
