An Immigration and Customs Enforcement (ICE) agent has been caught onnewly released bodycam footageadmitting he was uncertain of his target's identity during a marathon 10-hour standoff that paralysed a Vermont neighbourhood.

The high-stakes confrontation in South Burlington escalated into a bitter institutional row, with local police commanders and state officials pleading with federal agents to stand down to avoid a potential bloodbath.

The footage, part of a massive 100-hour evidence dump, shows Officer Colton Riley shrugging off his inability to name the suspect, stating, 'Assuming that's him, it doesn't matter.'

The operation, sparked by a reported vehicle collision involving an Immigration and Customs Enforcement car, drew hundreds of protesters and triggered a total breakdown in inter-agency cooperation.

Vermont's Public Safety Commissioner has since blasted the federal response, describing it as being 'out of alignment' with modern policing standards and warned of a permanent erosion of community trust.

As the ICE mistaken identity footage goes viral, the incident is being held up as a chilling example of the friction between federal enforcement mandates and local public safety concerns.

The tension in South Burlington reached a breaking point as local officers realised the federal agents on the scene were operating with a startling lack of specific intelligence.

When pressed by local police for the suspect's name, Officer Riley's admission of ignorance became a central point of the South Burlington ICE standoff controversy.

In the clip, a police officer asks a simple question, 'What's the male's name?' Riley, replies only, 'Um.'
