"...I can only assume that the Coast Gusard/Nazi/Dyke story inspired you..."
Your assumption is wrong. And let's not use inflammatory words like nazi, dyke, or even "rave party". As a matter of fact, the story I recounted is different. The army and police DESCENDED on an open air concert that was being conducted in line with county regulations.
(Yours occurred because you were IN the same space as the Navy ship; however I digress.....)
The example THIS story tells, is one of dramatic interference with excessive force of a peacefully gathered crowd for entertainment, or while Americans are out enjoying their so-called "freedoms".
"Jack-booted thugs", they are not.
There's another name for this and I'm not sure I've found it yet.
