Here are all kinds of interpretations
I have my interpretation, but there are more.
I think any interpretation should be read with this in mind:
Most people don’t realize that the Constitution is what the Government can’t do.
If some random worker at Wal-Mart wants to search your personal backpack, that is not a violation of your 4th amendment rights. You can’t take them to court over it.
If a police officer told the worker to do that, that worker is acting as an agent of the government so it’s illegal.
If a cop did it, it’s illegal.
However, the link I posted are interpretations from people who are professors, so hopefully they have a better understanding on what is the Government vs what is the individual.
A common way people interpret the 2nd amendment, is in two parts. You have the right to form a militia and you have the right to bear arms. Most people consider the Bill Of Rights to be everyone’s individual rights. So the 2nd amendment would apply to individuals as well as groups. That is, at least, how I was taught in college. I have an Associates in Criminal Justice and a good understanding of the Bill of Rights. I was taught it applies to the individual, that is also what I believe.
(And that is not me saying I am credible, just offering my background for my interpretation)
