The Trump administration is offering grants of tens of millions of dollars to cities across the US to create more Memphis-style enforcement surges – on the condition that they abandon progressive ideologies on policing.

The US Department of Justice says it will announce up to four finalist cities that will split $300m in grant funding under a federal “Model Cities” policing initiative (MCI) next month, setting the stage for some of the largest federal policing grants ever awarded to individual US cities.

In exchange for the funding, cities are required to comply with federal immigration enforcement requests, enact conservative policies on anti-homelessness rules, and potentially repay millions of dollars in the event of a surge in violent crime or “civil unrest”, according to a grant document.
