No president has ever attempted to use the military for domestic law enforcement "in such a wide variety of ways and on the scale" that President Trump has, says @josephanunn.bsky.social. That's dangerous to democracy and to public safety.

The effectiveness and cost of the National Guard deployment in D.C.
It has now been one year since President Trump declared a “crime emergency” in the nation’s capital and deployed thousands of members of the National Guard to its streets. Questions continue to mount ...

President Trump's deployment of National Guard troops in Washington DC "is designed to normalize something that should never be normal in this country: the use of the military as a domestic police force," @josephanunn.bsky.social writes.

Crime in DC isn’t an ’emergency,’ but normalizing troops in US streets is
It’s now clear that the deployment was never meant to be a quick response to an immediate crisis.

The American people should not accept troops in the streets as "just a fact of life," says @josephanunn.bsky.social "Armed military personnel standing on the street corners in an American city should never be normal."

Armed troops have patrolled D.C. for 1 year now. It's challenging democratic norms
The deployment is expected to cost in the billions after it was quietly extended until Inauguration Day of 2029.

My colleague @josephanunn.bsky.social puts it perfectly - Trump’s deployment of the National Guard on the streets of DC, which began one year ago today, is “designed to normalize something that should never be normal in this country: the use of the military as a domestic police force.”

Automatic license plate readers are having a moment - but probably not the moment their vendors are hoping for. John Oliver threw down the gauntlet last week in an episode highlighting many of the concerns about LPRs - incl that they allow the govt to go back in time and see where you've been. 1/19

Governors of many U.S. states and territories have sweeping power to use National Guard troops with relatively few legal constraints. Our new resource, accompanied by an interactive map, catalogues these laws and explains how legislatures can reform them to prevent abuse. bit.ly/4ainiev

It is now crystal clear who is obstructing reauthorization. Cornyn & other reform opponents would rather see Sec. 702 expire than allow reforms to protect Americans’ privacy. Sen. Wyden offered an easy path forward for extending the law. Reform opponents would prefer sunset. 2/2

Senator Cornyn just blocked a 9-month extension of Section 702 with a warrant requirement for backdoor searches. He then blocked a 5-week extension with no warrant requirement, just basic transparency measures. 1/2

The Posse Comitatus Act was created to limit when federal troops can be used against Americans. Four key reforms are needed to make sure the law holds up: bit.ly/47Qbde5

Why the Posse Comitatus Act Must Be Reformed
Significant exceptions and loopholes, along with a lack of enforcement mechanisms, undermine the law that prevents military involvement in law enforcement.

THREAD: This may be legal, but it raises a host of concerns. The Trump admin has inserted the military into civilian law enforcement in an ever-growing variety of ways. Individually, these are often minor. Taken together, they start to blur the line separating the military from civilian government.

Despite the president's threats, most of what the Trump admin has done in DC this past week is not repeatable anywhere else. Those concerned about federal military intervention in other U.S. cities should instead look to the Trump admin's actions in Los Angeles as a model for what is likely to come.
