If you get a pillager to fire its crossbow enough, the crossbow breaks, rendering the pillager passive.

How to duplicate: have a pillager fire at a villager behind a wall consisting of 3(I think) snow layers on top of a glass block. After about 20 minutes, the crossbow will break.

I like this bug,  but can you make it so villagers will not run away from them, and iron golems will not attack them?
