So I'll tell my mates:

I read on Indymedia that someone's blog said that a friend of the blogger had had a conversation with someone else in which it was mentioned that... oh never mind.

if you read the blog post it also shows this claim is supported by an article in the mirror earlier this month, you are kidding yourself if you think we are that far away from it.

The bogus claim is not supported by the Express (not Mirror) article, which is itself bullshit - the army is always on standby, and is always the last resort option for public disorder should the police totally lose control.

I've heard this joke before:
"Army goes on standby to avert May Day mayhem"
"Police and Army on Docklands anarchist alert"
"Army on standby to halt petrol blockades"
"Riot fear army on standby to move Gilligan"
"Army on standby for mass killings"
"Army on standby as prison staff prepare to go on strike"
"Army on standby as crisis endangers lives"
"UK government plans to put the army on standby to cope with Y2K"

Of course it's possibly just a scare tactic from the government etc but they do seem to have the right to kill us if they wish! This is what happens when your country is signed away to EU control (aka treason)

The right for some vaguely defined army or police force to shoot you dead with impunity is codified in EU law.
The EU has the power and authority to apply an instant death penalty to you,
under The Convention for the Protection of Human Rights and Fundamental Freedoms.
Better known to us as The Human Rights Act.

The Convention

Rights and Freedoms

Article 2

Right to life

1 Everyone’s right to life shall be protected by law. No one shall be deprived of his life intentionally save in the execution of a sentence of a court following his conviction of a crime for which this penalty is provided by law.
2 Deprivation of life shall not be regarded as inflicted in contravention of this Article when it results from the use of force which is no more than absolutely necessary:
(a) in defence of any person from unlawful violence;
(b) in order to effect a lawful arrest or to prevent the escape of a person lawfully detained;
(c) in action lawfully taken for the purpose of quelling a riot or insurrection.

UK law would view that the *necessary* use of force the same way, e.g. Section 3 of the Criminal Law Act 1967.

The right to life cannot be legally absolute, as that would cause unresolvable situations, on maternity wards for example.

The EU doesn't have any power or authority under the ECHR, it is not a signatory. You seem to be confusing the EU with the Council of Europe.

Whether it would be treasonous for a sovereign representative to sign away 'your country' to EU control is a purely academic question which need not trouble us.

that all states regardless of political persuasion have in common and which is recognised by all other states, is the use of violence against its own subjects/citizens.
