Sounds like he was shooting up the general area, and the van included. Maybe not even thinking about it and could have been shooting the back of a van, for all I know.

Given the background of the shooter, I don’t think he was thinking too much about the nuanced strategy and results, he was a 4-chan troll turned shooter, with maybe a bit of a libetarian bent, but mostly a generally nihilistic guy losing his mind in the cesspits of discussions.
