ART. 7036. [3.] In all cases where insurrection, domestic violence,
unlawful combinations or conspiracies in any State shall so obstruct or
hinder the execution of the laws thereof, and of the United States, so as
to deprive any portion or class of the people of such State of the rights,
privileges, immunities, or protection named in the Constitution and
secured by this act, and the constituted authorities of such State shall
either be unable to protect, or shall from any cause fail in or refuse
protection of the people in such rights, such facts shall be deemed a
denial by such State of equal protection of the laws of the United States,
to which they are entitled under the Constitution of the United States;

President, and it shall be his duty, to take such measures, by the
employment of the militia or the land and naval forces of the United

constituted authorities are in complicity with or shall connive at the
unlawful purposes of such powerful and armed combinations; and whenever,
by reason of either or all of the causes aforesaid, the conviction of such
offenders and the preservation of the public safety shall become in such
district impracticable, in every such case such combinations shall be
deemed a rebellion against the government of the United States, and during
the continuance of such rebellion, and within the limits of the district
which shall be so under the sway thereof, such limits to be prescribed by
proclamation, it shall be
