According to APs trial testimony. AP would shoot rabbits both with or without the silencer on his rifle, so whats the big deal anyway?
If that is what he said, then I agree. Moreover, for that calibre of rifle, I doubt the silencer made a lot of difference, to be frank.
Also, in Jeremy's case, we needn't assume he was intending to shoot rabbits when he went out on the evening of the 6th. around supper time. It may be that he just wanted to shoot
at them, i.e. to scare them away. If that was his purpose, then he would need a full-ish magazine and he would use the rifle without the silencer.
I've seen that before on farms. You go out and fire at the rabbits (or whatever vermin) as a way of shoo'ing them off, but without the intention of hitting them. Not everybody wants to shoot them, but may still need to shoot at them - for which a rifle is ideal, and you would not have the silencer attached under those circumstances.
