Can a grand jury create a precedent?

[I spent the winter writing songs about getting better]

Though I could see a grand jury doing nullification it'd obviously happen a lot less frequently than standard jury nullification since the type of crimes people like to nullify usually don't go before a grand jury. I imagine it'd happen more if the evidence indicates against the person in the way the law is literally read, but their actual role or responsibility isn't as large as the charges imply, an example might be a low level underling in a drug enterprise (like a bookkeeper) being charged the same way the top people are. However a grand jury doesn't need to give a reason to decline to indict, so precedent would be hard to extract from it. Grand jury nullification would just go down as officially that the prosecution failed to make a good enough case for an indictment.
