The last stop before the promised land looks like a landfill with people living in it. The Sun sent reporters into the expanding migrant camps in central Paris, and their report describes squalid camps at the source of what the paper calls the 'English Motorway' migrant route: the final leg that carries illegal migrants from French soil to what they've been sold as the easy life in the UK.

You can read the full report here, and I recommend you do, because the details matter. The Sun's own headline calls the camps rat-strewn, and the paper's reporting describes men preparing in these camps for the last leg of the journey to Britain.

Years of enforcement and security work taught me that logistics wins everything, and this is logistics. A camp is a staging area. A staging area is a pipeline. And a pipeline means someone upstream is getting paid.

The open-borders crowd never wants to talk about that part. They'll photograph the squalor and blame Europe's conscience. Fine. Ask them who runs the crossings. Ask them who collects per head. Nobody walks from North Africa or the Middle East to a tent in Paris for free. Every man in that camp paid somebody to get there, and the route to Britain doesn't run on good intentions either. That camp is a business operating in the open.

The draw is the destination. Britain is where the route points because the word on the route is that it's soft: work without papers, cash jobs, minimal consequences if caught. Whether that's fully true matters less than the fact that migrants believe it, as The Sun's reporting on the promised 'easy life' makes clear. Belief moves people. Smugglers know that better than any marketing department on earth.

I've covered this same machine for months on our side of the water: jet ski drops on California beaches, minors drugged and moved through ports of entry, smugglers bragging about their monthly take. The Paris camps are the same machine wearing a European license plate. The product is a human being. The customers are on both ends. And the camps grow because the route works.

Enforcement experience tells me how this ends, on either side of the Channel. Camps like this don't shrink on their own. They shrink when the route stops paying. When the crossing gets intercepted at a rate that makes the smuggler's pitch a lie, when the destination stops delivering the easy life, word travels back down the line faster than any government press release. The men in those tents talk to each other. That network is the real border infrastructure, and right now it's broadcasting that Britain is worth the fare.

A sovereign nation has every tool it needs to clear a staging camp. The Sun reports these camps are expanding, and an expanding camp tells you the route is still open for business. The men paying smugglers noticed, and they priced it in.

Call the route what the smugglers' customers call it, because the men selling the tickets are the only ones in this story telling the truth.
