With #1, strong leader probably means the strong-handed over-enforcing leader who’s tough on crime to solve problems. In your example I agree, but I’d also argue the leader is guiding society in that case and it takes everyone to solve problems.
With #3, I think it’s referring to a subset of actual citizens who are treated like “real” citizens over other citizens. Whether it’s by race, class, religion, etc. Some minority of the population is made the boogeyman.
With how trigger happy police are, the false positives would lead to more deaths than they prevent. And police would claim it’s justified because the machine told them so.
