The phrase in question is a bit strange, so I did a quick search online. There were only three links listed and all of them directed you an article located in ERIC. In case you are not familiar with ERIC, it is a database of academic, peer-reviewed journals which focuses mostly on education.
The phrase is confusing as it seems to have taken a bit of poetic license:
"the creatures" = the disabled children
"the federal swamp" = I presume its a name for the federal bureaucracy, equating it with a swamp (not so nice!)
