It's speculative, but at the Good execution exercise by Ross, the male voice at the end of the Ross recorded video saying "fucking bitch," might have been displeasure against Noem, for trying to forestall the very bogus killing practice ICE ostensibly intended to end and which Ross intentionally indulged in.
That's a Crabgass speculation, not one explicitly stated in the RawStory item.
RawStory did conclude its item, "Immigration officials stepping in front of vehicles has been a documented phenomenon for more than a decade. A 2014 internal review of the U.S. Border Patrol’s policies obtained and reported on by The Nation revealed that immigration officials had “intentionally and unnecessarily stepped in front of moving cars to justify using deadly force against vehicle occupants.”
In Minnesota, there is no statute of limitation for murder. Hopefully Ross understands why, or learns.
