How do the people feel?
After conducting a survey of 27 random people, I have compiled two graphs. In the first graph, you can see that a majority of the respondents believe that mandatory police checkpoints are unconstitutional. A small amount believe they are constitutional and a fair amount don't know. We will ignore the people who don't know because that input is not helpful. The ones who believe it is constitutional either have a misunderstanding of the bill of rights, trust the Supreme Court's decision, believe the state's interest outweighs the people's interest, or use some other method to decide constitutionality. All in all, we can safely generalize that a good majority of people believe the checkpoints are unconstitutional.
In the second graph, something strange happens. A majority of people respond that they believe the checkpoints should continue to operate. This is strange because in the first graph, a majority of people said that they were unconstitutional. If the Bill of Rights was created to safeguard the people's rights as citizens against unfair governmental operations, then why would anyone allow something that violates this continue to happen? Aren't people worried about their rights as citizens? My inference from this data is that the answer is no. This is a big problem because once we trust the government to protect our liberties, liberties meaning freedom from government authority, they have the go ahead to violate these liberties since there is nothing to stop them but themselves. Many people today are very trusting of their government. This doesn't sound so bad at first but since government and politicians have never had a steady reputation of honesty or fairness, when we trust them with things so important as our freedom, we cannot expect them to act honestly or fairly with those things because their track record is not great. This doesn't necessarily mean that they will create a police state or take away all of our rights. However, we must be very careful because if we allow them to do things which violate our rights even in ways we might consider small like these checkpoints, the next more severe violation is so much easier to reach.
