Congress finds the following:
(1) The Second Amendment to the Constitution states that a `well regulated militia, being necessary to the security of a free State, the right of the people to keep and bear arms, shall not be infringed', and Congress has repeatedly recognized this language as protecting an individual right.
(2) In the wake of Hurricane Katrina, State and local law enforcement and public safety service organizations were overwhelmed and could not fulfill the safety needs of the citizens of the State of Louisiana.
(3) In the wake of Hurricane Katrina, the safety of these citizens, and of their homes and property, was threatened by instances of criminal activity.
(4) Many of these citizens lawfully kept firearms for the safety of themselves, their loved ones, their businesses, and their property, as guaranteed by the Second Amendment, and used their firearms, individually or in concert with their neighbors, for protection against crime.
(5) In the wake of Hurricane Katrina, certain agencies confiscated the firearms of these citizens in contravention of the Second Amendment, depriving these citizens of the right to keep and bear arms and rendering them helpless against criminal activity.
(6) These confiscations were carried out at gunpoint by nonconsensual entries into private homes, by traffic checkpoints, by stoppage of boats, and otherwise by force.
(7) The citizens from whom firearms were confiscated were either in their own homes or attempting to flee the flooding and devastation by means of motor vehicle or boat, and were accosted, stopped, and arbitrarily deprived of their private property and means of protection.
(8) The means by which the confiscations were carried out, which included intrusion into the home, temporary detention of persons, and seizures of property, constituted unreasonable searches and seizures and deprived these citizens of liberty and property without due process of law in violation of fundamental rights under the Constitution.
(9) Many citizens who took temporary refuge in emergency housing were prohibited from storing firearms on the premises, and were thus treated as second-class citizens who had forfeited their constitutional right to keep and bear arms.
(10) At least one highly-qualified search and rescue team was prevented from joining in relief efforts because the team included individuals with firearms, although these individuals had been deputized as Federal law enforcement officers.
(11) These confiscations and prohibitions, and the means by which they were carried out, deprived the citizens of Louisiana not only of their right to keep and bear arms, but also of their rights to personal security, personal liberty, and private property, all in violation of the Constitution and laws of the United States.
The above is the finding of a congressional investigation, and you insist that it didn't happen?
