I would be concerned about ideologically incorrect research, innocent mistakes, non-research-related activism, working for a disfavored person, being part of a disfavored ethnic group, etc.
This is similar to how privacy-conscious people are told that “if you don’t have anything to hide then why are you so concerned about actually hiding things?”.
This is my thought Everytime someone defends increasing government power and authority. They always assume the government is going to act in good faith and never use the power in a harmful way. Almost as if they've never read a history book.
