You can bet that to get to this point where FEMA has taken the action it has, there have been multiple warnings and time to fix the issues that had been identified. In most cases these are composite teams made up of first responders and other specialized personnel from multiple agencies. Keeping the team current on training and accounting for the funds and equipment is not an easy task. For a number of years I sat on a board that oversaw the Washington State Urban Search and Rescue Task Force. There were always issues of audits to be prepared for and the apportionment of training and how the funds were being used could be contentious at times. You need a strong administrative agent to hold everyone accountable for their responsibilities. I expect that this lack of control in New Mexico was one of the things that led to their undoing.
Now that they have officially lost their funding you can bet it will not be forthcoming again for a New Mexico team for a long time to come.
