What exactly is the "trap" in Slaughterhouse?

[aabicus]

From an in-universe perspective, I don't fully understand what the Payday gang was doing to trick the SWATs. They brought the gold to a container outside, then they fill the adjacent container with lit gasoline, then the crane lifted the gold away. What did that trap accomplish?

I don't exactly remember it, but the crew covered their tracks in 2 steps (both employing the use of gasoline fires) before making their grand exit.

Firstly, they set fire to the dump of tires nearby outside the slaughterhouse to buy enough time for the crew to blind nearby air support and recon, rendering them useless.

Secondly, under the cover of heavy smokescreens, the crew lifts the gold and loads them into a low profile truck and prepares an "exit" container to ensure no law enforcement can follow them when Bain opens up the exit path using containers to the unmarked truck.

The last crew member that passes the trapped container lights the fire to ensure no one can follow them or retain visual of where the crew went as they board the truck to a clean getaway, leaving the police to deal with a large crime scene and 2 hefty fires to contain.
