Is there a caravan at all?
Is the media doing focused interviews? Personal stories of people in the caravan? Are there journalists embedded with the caravan?
I have something of a hippie friend who would love to walk with this caravan and snap pictures of the journey, the people in it, etc. She's a journalist with a good heart, if a bit naive to the realities of some of these things. Where are the people like her? Where is their coverage of this?
What we do see is a bunch of footage strung together to create the impression of a caravan. However… How is it moving? What roads is it taking? It simply appears at the edge of a city, things happen on camera, and then it disappears into the ether before it pops up at another city.
These are CIA units trained in propaganda warfare. If we can make Germans believe in a massive fucking army of nothing … I'm pretty sure the proverbial they can cook up a migrant mob for funzies.
All of this means that they can hit with agitators and other assets in place at the border who have trained for a very long time and studied border patrol behavior. The media provides cover for the special operations forces who will go to action with the rent-a-mob saturating the attention.
