Right to Travel vs. Secure Borders

How do you solve this dilemma?

A drivers license is required to operate a motor vehicle upon the streets.
A license is something that you get when you "ask permission" to do something.
We as Citizens have the Right to Travel, free movement upon the land. We don't need to ask permission to use the streets.

The drivers license seemed like a good idea, as some people were abusing the Right to Travel by endangering others who also used the streets. It was first meant to be a proficiency test so that people knew how to safely use the streets.
Then, it was used to remove those from the streets that were deemed dangerous to others using the streets (such as drunk drivers).

There are now "random checks" along the roads. People are stopped and asked different questions by law enforcement authorities. At times the questions are about drinking, some times to see if you have illegal produce (fruit police) and other times to check your identity (to see if you are an illegal alien).

And the whole drivers license thing has become way more that just making sure people are driving safely. If you don't pay your child support, ALL your licenses (driving and professional) can be taken from you.

There are videos on Youtube with people refusing to answer questions at these random check points. And there is advice by defense attorneys to NEVER answer a question that is asked of you by police. Plus, the "illegal aliens" are being coached to "shut up", don't say a word if you are stopped by police.

How do you balance another person's Right to Travel and your Right to Life (not getting killed by a drunk driver)? In the old days, if you came into town with your wagon and horses, and you lost control of the horses (say, you were drunk), and killed someone -- you were charged with manslaughter.

If we want our borders to be secure, and the borders are not... how would you solve the problem? Previously, the states handled immigration. But now it is the feds. And, it is much easier to travel with cars than with wagons.

We are a young country. A very large country, with a mix of immigrants (legal and illegal), children (grandchildren, great grandchildren, etc) of immigrants and slaves and Native Americans.

We need to find balance.
