Lea, who holds a Ph.D. in cryptography and serves on the USENIX board, will discuss designing systems that make doing the right thing easy. See more about the session here: www.usenix.org/conference/u...

From ransomware to state-sponsored actors, security is deeply entangled with people, systems, and incentives. The key lesson is that security isn't just about fixing bugs, but about understanding motivations and building alliances. 2/3

ICE activity is happening across the country, and will likely draw protests in many places. Trump is authorizing military deployment nationwide, regardless of whether protests involve violence *or are even happening yet.* 14/19

Moreover, the line between military and civilian government is one of the most critical protections for democracy. An army turned inward can quickly become an instrument of tyranny. That’s why domestic deployment should be an absolute last resort. 11/19 www.brennancenter.org/our-work/res...

Civil unrest should be handled by civilian law enforcement except in the most extreme situations. Soldiers are trained to fight and destroy an enemy; they aren’t trained to safely handle and deescalate civil unrest situations. 10/19 www.judiciary.senate.gov/imo/media/do...

The memorandum says that the Guard will be protecting ICE personnel and federal property. As a practical matter, this will almost certainly involve serving basic police functions, such as physical crowd control, that the military normally isn’t allowed to perform. 9/19

But it would be a mistake to focus too much on which statutory power is being used here. What matters it that Trump is federalizing the Guard for the purpose of policing Americans’ protest activity. That’s dangerous for both public safety and democracy. 8/19

Trump is instead relying on a statute, 10 USC 12406, that allows the president to federalize the Guard when there is a rebellion against the authority of the U.S. government or when “the President is unable with the regular forces to execute the laws of the United States.” 6/19

Ordinarily using federal troops (including federalized National Guard forces) to suppress civil unrest would be illegal under the Posse Comitatus Act. But Congress can legislate exceptions. The relevant exception here is the Insurrection Act. 4/19 www.brennancenter.org/our-work/res...

That’s alarming enough. But Trump has also authorized deployment of troops anywhere in the country where protests against ICE are occurring or are likely to occur, even if they are entirely peaceful. That is unprecedented and a clear abuse of the law. 2/19
