When the Sons patched in Indian Hills Season 1 Episode 4
When the MC patched in Indian Hills there was a dust up with the Mayans. Jax kicked over their bikes outside of a bar, got their attention and led them back to the Indian Hills clubhouse. The Mayans sat outside on their bikes and began shooting through the clubhouse door. The MC was ready and most of them snuck out the back and around the sides to flank the Mayans and began shooting back at them.
The Mayans hit two guys, but the Sons didn't hit a single Mayan. There were a LOT of Sons shooting at a bunch of closely grouped stationary targets. They took a lot of shots and missed every time.
I don't know why the writers made them such lousy shots.
