Lock down information sources such as the news media. Ensure that all information which is released is fully vetted to support government policies and decrees.
Once information is fully controlled, police activity to enforce government policy can proceed unabated with little fear of meeting organized resistance. President Trump appears to have learned quite well from history.
If by 'learned quite well from history', you include the last 8 years, then you're making a reasonable point. Obama spent 8 years weaponizing the federal government, and then handed it over to Trump. Think about that next time your champion is elected.
