Writ of Habeas Corpus

Individuals complaine that the government not abiding by the term Habeas Corpus is not legal.

First the term Habeas Coprpus is defined as:

"(that) you have the body. It refers to various writs requiring that a detained person be brought before a court to decide the legality of the detention or imprisonment."

The Constitution, Article I, section 9, paragraph 2

"The privilege of the writ of habeas corpus shall not be suspended, unless in cases of rebellion or invasion the public safety may require it."

Article III, Section 3 paragraph 1,

Treason against the United States, shall consist of levying war against them, or in adhering to their enemies, giving them aid and comfort. No person shall be convicted of treason unless on the testimony of two witnesses to the same overt act, or on confession in open court.

Paragraph 2,

The Congress shall have power to declare the punishment of treason.

What part of citizens or foreigners plotting to destroy the United States is not rebellion or invasion? It appears to me people caught should be tried on the spot and hanged for spying not imprisoned for treason.
