Julie's friends

1) Friends of Julie went to Tom's place and told him to stop harassing her.

2) Julie's friends went to Tom's place and told him to stop harassing her.

Can one use '2' instead of '1'?

I think technically '2' means all of Julie's friends went to Tom's place, but I think that '1' could be used instead of '1', at least in casual speech, especially if the context makes things clear. I'd imagine two or three of her male friends went and talked to Tom....
