In this question, we cannot reference the specific case that you used in your Critical Thinking Assignment as we do not know what this is. However, we can still answer the other questions.
I believe that citizens should trust the government to protect our civil liberties. This is because the government has the power to oversee all businesses and institutions of the country. The government is more likely to be able to identify violations to our liberties, as well as punish those who commit them. The United States has not always succeeded in protecting these liberties, but they have done a better job as time goes by. There is a constant trend in government of allowing for more liberties and better protection for a larger number of people.
As for now, I believe that the current protections that we have are enough to protect our civil liberties and rights. Under the law, all groups are equal, regardless of gender, race, age or sexual preference. However, I do believe that we would benefit from additional regulations to the media. Fake news are a real problem in the present, and fake news that have hate or intolerance as motivation can greatly damage our society.
