That Trump II is killing its way through every level of Iran's leadership until the unqualified recent hires are in charge is consistent with the notion that hegemons always try to export their ideal regime type.

MIT Sloan's Masters in Finance Program remains best-in-class for financial economics (not financial engineering, where other programs are better). The industry eats up our graduates because they understand the math AND the economics. mitsloan.mit.edu/sites/defaul...

Former ICE agent: My first day training new cadets, I received secretive orders to teach them to violate the Constitution by entering homes without a warrant. I watched ICE cut classes that teach our legal system, firearms training, use of force, lawful arrests, and the limits of officers' authority

This is the most fundamental form of constitutional defiance. Marbury v. Madison, THE formative decision in the separation of powers, says β€œIt is emphatically the province and duty of the judicial department to say what the law is.”

So when a judge says β€œthe law is X,” the law is X.

 MEMORANDUM FOR: All ICE Personnel

FROM: Todd Lyons Acting Director 
SUBJECT: Utilizing Form I-205, Warrant of Removal 

On January 20, 2025, President Donald J. Trump issued Executive Order 14159, Protecting the American People Against Invasion, directing the Secretary of Homeland Security to "ensur[e] the successful enforcement of final orders of removal." 90 Fed. Reg. 8443, 8444 (Jan. 20, 2025) (E.O. 14159). Essential to the removal of aliens subject to final orders of removal is the ability to locate and arrest them. To this end, certain supervisory immigration officers within both Enforcement and Removal Operations (ERO) and Homeland Security Investigations (HSI) are authorized to issue an administrative warrant, Form I-205, Warrant of Removal (Form 1-205), for the arrest of an alien with a final order of removal. 8 C.F.R. Β§ 241.2(a)(1). All U.S. Immigration and Customs Enforcement (ICE) special agents and deportation officers are authorized to execute Forms 1-205. 8 C.F.R. Β§ 287.5(e)(3)(iii) - (y)

Although the U.S. Department of Homeland Security (DHS) has not historically relied on administrative warrants alone to arrest aliens subject to final orders of removal in their place of residence, the DHS Office of the General Counsel has recently determined that the U.S. Constitution, the Immigration and Nationality Act, and the immigration regulations do not prohibit relying on administrative warrants for this purpose. Accordingly, in light of this legal determination, ICE immigration officers may arrest and detain aliens subject to a final under of removal issued by an immigration judge, the Board of Immigration Appeals (BIA), or a U.S.

Arrow) district court judge or magistrate judge in their place of residence.23 ICE immigration officers should consider all available enforcement mechanisms, including the use of a Form 1-205 to arrest an alien in their place of residence, to achieve the requirements of E.O. 14159 in accordance with applicable law and policies. This guidance informs the use of Forms 1-205 and provides to ICE law enforcement personnel a reminder of the general limitations and exceptions that may apply when effectuating arrests in an alien's residence. General Guidelines ICE law enforcement officers receive extensive training on the legal and procedural requirements for making administrative and criminal arrests. ICE personnel must remain cognizant of all existing laws and policies pertaining to arrests when carrying out civil immigration enforcement actions. Prior to entering a residence to conduct an administrative immigration arrest pursuant to Form I-205, officers and agents must ensure the Form 1-205 is properly completed and is supported by a final order of removal issued by an immigration judge, the BIA, a U.S. district court, or a magistrate judge. This is essential because that order establishes probable cause. Officers and agents must also have reason to believe that the subject alien resides at and is currently located in the address where the Form I-205 is to be served.

ICE secretly told its officers that any time someone has been ordered removed, ICE can break down their door.

It has been accepted for generations that the only thing which can authorize agents to break into your home is a warrant signed by a judge. No wonder ICE hid this memo!

Please don't think anything is back to normal in Minnesota. Nothing is normal.

I know we’re strong. Don’t know if it’s enough.

If you don't live here, your Minnesota friends may tell you that it's going to be okay but I think a lot of that is them being nice so you won't worry.

It's bad here.
