Two labourers stand on the roof of a house in Kenner, outside New Orleans, as US Border Patrol agents clamber up a ladder, getting closer.
As the agents move in, trying to arrest them, the men step to the roof's edge, poised in an apparent act of resistance - but it's too high to jump.
On the ground in the mostly Latino neighbourhood, an officer trains his weapon towards the rooftop while a sniper moves into position. Now, neighbours, activists, and crews of local press are gathering at the scene, watching in bewilderment: US President Trump's new front line on immigration enforcement has just arrived.
It is day one of "Catahoula Crunch", as the Department of Homeland Security (DHS) has labelled its operation, taking its name from an American leopard dog known for being well-muscled, powerful and territorial.
"These people came to work today to provide for their families and themselves," said Zoe Higgins, an activist documenting the Border Patrol operation in New Orleans.
