Trump’s response to the LA protests has been a critical point this week for US politics, as the public onlooks the face-off of protesters against Trump’s immigration policies and his excessive military backlash.

US-trained legal academic Auckland University Associate Professor Scott Optican says the move threatens core rule of law and use of force principles that have guided past American presidents, saying this purposeful escalation allows him to employ “anti-immigrant rhetoric to stoke fear and galvanise his political base”

University of Auckland’s Politics and International Relations Associate Professor Maria Armoudian also said it’s yet more evidence of Trump’s unchecked power and the country’s apparent slide into authoritarianism.

Producer Sara spoke with Scott Optican about the implications of Trump’s response to these protests, and the discourse around immigration. To start, she asked him to explain how Trump’s use of force threatens the principle of appropriate use of force, and the rule of law.
