The attempted assassination of U.S. Rep. Gabrielle Giffords, D-AZ, and the murder of six innocent bystanders, at a meet and greet with constituents on Jan. 8, was a shocking and tragic event nationwide. Unfortunately, trying to kill American politicians is neither unique nor new.

On Jan. 30, 1835, a house painter named Richard Lawrence, who apparently believed he was King Rcihard III of England, and that the American President Andrew Jackson was withholding his rightful treasure, approached Jackson as the President was exiting a funeral in Washington. Lawrence fired a flintlock pistol at Jackson's back from about 15 feet away. It misfired. Lawrence stepped closer to point-blank range and fired a second flintlock. It also misfired. The President, with the aid of Davy Crockett and others, subdued Lawrence, who was committed for life for insanity.

On May 22, 1856, in the heated times leading up to the Civil War, pro-slavery Sen. Preston Brooks, D-SC, walked across the floor of a near empty U.S. Senate chamber and, with a gold-tipped hard wood cane, beat Sen. Charles Sumner, R-MA, within an inch of his life, while Sumner struggled in vain to get up from his seat. Sumner had attacked pro-slavery lawmakers in speeches. He went through extensive rehabilitation before returning to the Senate. Brooks received dozens of canes from Southern admirers.

More than a few people wanted to kill Abraham Lincoln, and there were at least two attempts on life before John Wilkes Booth succeeded in murdering the 16th President. Lincoln's entourage to Washington for his inauguration in 1861 reportedly eluded assassins waiting to ambush the President-elect in Baltimore and, in 1864, during the Civil War, someone took shots at Lincoln as he rode by, causing his horse to bolt.

On April 14, 1865, which was Good Friday, Booth rushed up behind Lincoln at Ford's Theatre in Washington and shot him in the back of the head. Lincoln died the next day. Booth was shot and killed 12 days later.

Garfield died at the New Jersey resort 11 weeks later. Guiteau was hanged.

William McKineley, the nation's 25th President became the third assassinated Chief Executive on September 6, 1901, at the Pan-American Exposition in Buffalo, NY. He also was shot twice, by an anarchist, Leon Czolgosz, who believed that the wealthy were exploiting the poor. Czolgosz was beaten almost to death on the spot, but lived to be electrocuted in October.

Vice President Theodore Roosevelt became President and won re-election. But, when out of office in 1912 and campaigning to get back in, TR took a bullet to the chest fired by John Schrank, a saloon-keeper who believed McKinley's ghost had told him to revenge his death. The bullet, from a .38 caliber revolver, was slowed by Roosevelt's metal glasses case and his folded, 50-page speech. Roosevelt gave the speech with the bullet in his chest, saying It takes more than one bullet to bring down a Bull Moose! He never had the slug removed. Schrank went to the insane asylum.

TR's cousin, Franklin D. Roosevelt , not yet sworn in for his first of four terms as Chief Executive, was in Miami on February 15, 1933, when an Italian immigrant with health and mental problems, Giuseppe Zangara, fired five shots at FDR and those with him. Roosevelt was not struck. Four people were wounded and the mayor of Chicago, Anton Cermak, was killed. There is speculation that Cermak and not Roosevelt was the target and that Zangara was working for Chicago gangster Al Capone. That's never been proven. Zangara was executed in March, 1933.

First an FDR ally, then a staunch opponent who was considering a presidential run against Roosevelt, Sen.

Weiss was shot by Long's bodyguards over 60 times and died at the scene.

In 1975, President Gerald Ford escaped two assassination attempts within two weeks.

On March 30, 1981, only 69 days into his presidency, Ronald Reagan was shot by John Hinckley, Jr. as he exited the Washington Hilton Hotel in D.C. Reagan and three others, including White House Press Secretary James Brady were wounded. Reagan was rushed to an area hospital. He suffered a punctured lung, but the prompt attention allowed him to recover fairly quickly. Brady, more severely injured, went on to become an advocate against guns and gun violence. Hinckley had an obsession with actress Jodie Foster from her role in the Martin Scorsese film Tax Driver in which the title character contemplates assassinating a U.S. Senator who is running for president. Hinckley was judged not guilty by reason of insanity. He remains confined to a psychiatric hospital.

On October 29 of the same year, Francisco Martin Duran fired 29 shots with a semi-automatic rifle at the White House from a fence overlooking the north lawn, thinking Clinton was among the men he saw on the lawn. Clinton was, rather, in the White House. No one was hurt. Three tourists tackled Duran, who got 40 years.

The pin was pulled but the grenade did not explode because the would-be assassin had wrapped a handkerchief too tightly around it. Arutyunian received a life sentence.
