November 22nd, 1963

On Saturday it was 45 years since JFK assassination. He was killed because he wanted to change things.
President Kennedy was assassinated in Dallas, Texas, at 12:30 p.m. Central Standard Time on November 22, 1963, while on a political trip to Texas. He was shot twice in the neck and head, and was pronounced dead at 1:00 p.m. Lee Harvey Oswald was arrested at a movie theater at about 1:50 p.m. He denied shooting anyone, claiming he was a patsy, and was killed by Jack Ruby on November 24, before he could be indicted or tried.
President Johnson created the Warren Commission—chaired by Chief Justice Earl Warren—to investigate the assassination. It concluded that Oswald was the lone assassin, but this remains disputed by some scholars, eyewitnesses, and the 1979 findings of the House Select Committee on Assassinations. Conspiracy theories about the assassination and supposed cover-up continue to circulate.

Around the world there are memorials that are impressive.
This is the one in Texas, where the assassination happened

While aesthetically simple, the intent of the Kennedy Memorial is often misunderstood. Renowned American architect Philip Johnson designed the structure as a thoughtful piece of art intended for reflection and remembrance. Johnson’s design is a “cenotaph,” or open tomb, that symbolizes the freedom of John F. Kennedy’s spirit.

The memorial is a square, roofless room, 30 feet high and 50-feet-by-50-feet wide. Visitors enter the room after a short walk up a slight concrete incline that is embossed with concrete squares. Once inside, visitors see a low-hewn granite square in which John Fitzgerald Kennedy’s name is carved. The letters have been painted gold to capture the light from the “floating” white column walls and the pale concrete floor. These words are the only ones in the empty room.

The other one that is really impressive is in Jerusalem.

The memorial, 60 feet high, is shaped like a felled tree trunk, symbolizing a life cut short. Inside is a bust of John F. Kennedy, with an eternal flame burning in the center. It is encircled by 51 columns, each bearing the emblem of a state (50 states and the District of Columbia). [1]The monument was built in 1966 with funds donated by Jewish communities in the USA. It was designed by the Israeli architect David Resnick.
