Just thinking of something that's been bugging me and I thought of it again while I'm rewatching the episode.
Obviously Hale and Roosevelt think the Sons killed the Russians (which they did) but honestly they have NO proof. I mean they wore gloves and etc. (I don't recall Jax when he was doing the stabbing) but even then I expect them to white the knife.
But one, they didn't have audio and then guns being taken doesn't mean it's the Sons. Second, is HOW did they not hear the shot of the gun (I'm assuming they were doing the shooting near the wedding (the one Clay was shooting). I mean was the music really that loud.

Sorry had to get that out since it was bugging me
