There's a storm of controversy over a just-opened exhibit of evidence from some of the most sensational cases in U.S. history.

The exhibit includes the bloody gloves from the O.J. Simpson murder trial.

A police photo shows screen idol Marilyn Monroe dead in her bed from an overdose of sleeping pills.

The rope used to tie up actress Sharon Tate when she was slaughtered by the Manson family is also in the exhibit.

Her sister Debra is outraged.

"It's very disturbing, number one I didn't get any notice that this was going to occur, but these are very personal artifacts to me," Debra Tate said on Larry King.

The bloody shirt Senator Robert Kennedy wore the night of his assassination in 1968 is also in the exhibit. But after the Kennedy family objected, the LAPD agreed to remove it from the display.

Police issued an apology to the Kennedys, saying:

"The last thing we want to do is traumatize a victim's family."

The LAPD put together the exhibit at the Palms Casino Resort in Las Vegas for a conference of homicide detectives. 

"It's so much history, these are very real stories that come to life when you see the evidence," Chief Charlie Beck said.

But Kim Goldman, sister of Ron Goldman, who was murdered alongside O.J. Simpson's ex-wife, told Larry King the gruesome evidence should never be put on public display.

"When their case closes, we still have a life to live and we still have the devastation to work through," said Goldman.
