Just watched the first 5 seconds of the video - first thing I hear clearly:

"Guards, are you here on your oath today?" ------> Freeman bullshit

(Any knowledgeable legal professionals care to explain if the argument is nonsense or not?)

Everyone you will encounter, in the "Legal" or "Lawful" worlds, will have taken an Oath in order to claim their 'title'. This includes Judges, Magistrates, Bailiffs, Notaries, Solicitors, Lawyers and ... of course ... Policymen.

Acting within their Oaths, they are what they claim to be. And, in this case, they are all Peace Officers ... because that is what their Oaths state.

Acting outside their Oath, they are not what they claim to be. Acting outside their Oath, they are simply "Joe Soap" (maybe in in some kind of uniform, but Joe Soap nonetheless).

In a Court de jure (Common Law Court), for example, a Judge will be on his Oath. However, as a Judge, he will be offered 'employment' to run Courts de facto (Courts of Arbitrations of disputes). In these Courts, Magistrates and Judges are not on their Oaths. Thus they are not what they claim to be. They are nothing more than Joe Soap.

They can - ALL - be put on their Oaths by saying "I'm putting you on your Oath. Under God, so help me God. Now we have a Contract".

A Judge or Magistrate then has two options. Either to recuse him- or her-self, or to continue under Oath, to PROTECT YOU, and your Rights in Law. They usually choose the former, and so get up and leave the Bench.

A Bailiff or Policyman likewise. Having put a Bailiff on his or her Oath, they become Peace Officers, and are there to PROTECT your Rights. If a Bailiff arrives with a Policyman, put them both on their Oaths. If the Bailiff then proceeds as they do normally ... in other words continues to threaten ... then you can TELL the Policyman to "Arrest that man (woman), and I'm placing him or her into your safe custody". If the Policyman fails to react to that, say: "Who is your boss? I'm going to have you BOTH arrested for pretending to be what you are not."

Utter BS. Jim Corr would be proud.

Democracy is essentially mob rule & if enough people want something they will get it - thats how it is supposed to work

"I'm putting you on your Oath. Under God, so help me God. Now we have a Contract".

-I will faithfully discharge the duties of a member of the Garda Síochána with fairness, integrity, regard for human rights, diligence and impartiality, upholding the Constitution and the laws and according equal respect to all people,

-while I continue to be a member, I will to the best of my skill and knowledge discharge all my duties according to law, and

-I do not belong to, and will not while I remain a member form, belong to or subscribe to, any political party or secret society whatsoever.”.

What parts of it are utter BS?

Just saying it's utter BS is scoffing. It's not addressing why (or what parts) are utter BS. I think its important to challenge this stuff with facts.

I do not see how "invoking" the above oath puts someone at an advantage?

A Bailiff or Policyman likewise. Having put a Bailiff on his or her Oath, they become Peace Officers, and are there to PROTECT your Rights. If a Bailiff arrives with a Policyman, put them both on their Oaths. If the Bailiff then proceeds as they do normally ... in other words continues to threaten ... then you can TELL the Policyman to "Arrest that man (woman), and I'm placing him or her into your safe custody". If the Policyman fails to react to that, say: "Who is your boss? I'm going to have you BOTH arrested for pretending to be what you are not."

The oath thing could have been to highlight the "upholding the Constitution" bit, it could also have been used like @Barney Gumble said.

I think the argument in the vid was that the constitutional protections trumped the law being invoked by the deputy sheriff.

A JUDGE was challenged by a defendant yesterday to produce his oath of office before proceeding with a case being heard at Wexford District Court.

Declaring that he was before the court “under duress”, Bobby Oliver Sludds (29), Ballagh Cove, Enniscorthy, Co Wexford, said Judge David Anderson had no jurisdiction to deal with the case unless he first produced his oath.

“Where did you read that?” asked the judge.

“The Constitution. It says that a judge must offer up his oath when requested and I am asking you, do you have your oath?” said Mr Sludds, before picking up a copy of the Constitution and quoting from it at length.

“This is not a quiz, I ask the questions. I made my oath in front of the Chief Justice and I have no idea if he kept a record or not,” the judge replied.

“Do you speak English or legalese?” replied Mr Sludds, before putting down the Constitution and picking up a copy of Black’s Law Dictionary.

Quoting the precise definition of “summons”, Mr Sludds proceeded to dispute the validity of the summons issued by the court, in which he was charged with a number of motoring offences in Enniscorthy in April 2010.

“These offences are fraudulent and I’m not this Bobby Oliver Sludds you speak of,” he said. “That’s not me and this fictitious claim is a fraud on this court. This is not my name. I’ve been taken here against my will.”
