Haha, the only ones to contribute to this country's demise are those who choose to continue to support the status quo re the establishment....whether that's a tory or a Tony Blair.....continued disregard of social justice and the needs of the British people, if that makes me a Trotsky then so be it.
Who are 'their' here? And which of "our" institutions are being 'marched through' specifically. This statement indicates a large influx of people into an institution, so please let me know how many of the people whom you refer to as 'marching through our institutions' have 'marched' into which of our institutions?
Without specific facts to back this up, it sounds a bit generalised and paranoid, so please flesh out your claim a little (as you usually do so obligingly when asked in the past!) so I can see where we need to fix the problem to which you refer.
There can only be prosecutions if there is evidence of the commission of a criminal offence. Being incompetent or negligent is generally not a criminal matter (outside of road traffic law, health and safety or manslaughter).
To state the obvious, signatures on a petiion or a belief in a whitewash are not evidence.
