The fatal shooting of a woman in Minneapolis by a federal law-enforcement officer is laying bare the sharp divides in American politics – and threatening to inflame an already contentious debate over immigration policy.

The incident took place in broad daylight. There are multiple videos taken by bystanders from various locations. And yet even the basic facts are being disputed.

Almost immediately after the shooting, two starkly different accounts began to take shape. Any ambiguities in the videos shared online were seized upon - different angles and different screengrabs were used to push a particular narrative.

And on the public stage, state and federal officials openly disagreed.

According to Homeland Security Secretary Kristi Noem, the driver – 37-year-old Renee Good – was to blame. As she drove away from ICE officers, she "weaponised her car" in a "domestic terror attack", Noem said.
