Well, I'm glad that you realize that your desires go directly against against the Constitution.
But that’s not what I said or “realized” at all.
The Posse Comitatus Act simply prohibits federal authorities from acting on behalf of state and local law enforcement and from enforcing domestic policy.
You must have forgot that immigration is a federal matter?
That's not what the Posse Comitatus Act says.
From and after the passage of this act it shall not be lawful to employ any part of the Army of the United States, as a posse comitatus, or otherwise, for the purpose of executing the laws, except in such cases and under such circumstances as such employment of said force may be expressly authorized by the Constitution or by act of Congress ; and no money appropriated by this act shall be used to pay any of the expenses incurred in the employment of any troops in violation of this section and any person willfully violating the provisions of this section shall be deemed guilty of a misdemeanor and on conviction thereof shall be punished by fine not exceeding ten thousand dollars or imprisonment not exceeding two years or by both such fine and imprisonment.
The Posse Comitatus Act makes it illegal for the military to be used in the enforcement of any laws on US soil. It is not limited to prohibiting the military from enforcing "state and local matters".
Immigration law is a law. The military cannot be used to enforce the law in this country.
