Plot hole: When the guys break into the safe house and free the witness against Bobby, they are wearing masks to hide their identities. Yet after freeing the witness, Jax and Tig decide to get involved in a fist fight inside the house which would leave their DNA all over the place. Since both are undoubtedly on the police database, it would take no time at all for the police to find at least two of the culprits who assaulted two officers, an ATF agent and intimidated their star witness.
Continuity mistake: When Opie is talking to Jax about Donna. He pushes his hair out of his face and 2 strands fall down, Next shot his hair is all slicked back without him touching it.
Chosen answer: The First 9 wore these, as can be seen on old pictures. They later switched to leather, but Piney just never did.
