At this location? When you say pellets in the side of the van, do you mean embedded or just dings? If embedded I doubt it would be a BB gun?
There isn't an awful lot anyone can do if some scrotes decide to target you.
I carry a strong catapult for target practice

and a shillelagh as a walking aid

. The idiots will no likely be long gone before I can do anything but it does give a feeling of security to some extent.
