Tupac's Alleged Killer Keefe D Too Dangerous for Bail, Prosecutors Say

The state of Nevada is pushing back on Duane "Keefe D" Davis' request to be let out of jail ahead of the trial ... because they insist Tupac Shakur's alleged killer is just too dangerous.

For those unaware, Keefe D's lawyers asked a judge last week to release him from custody on his own recognizance before his trial, which is currently set to start in June ... and if the court wouldn't allow it, asking instead to set his bail no higher than $100k.

According to new docs, obtained by TMZ, prosecutors say Keefe D's request is absurd, and they provide several reasons why he shouldn't get to walk free until his trial. For instance, they claim he's a former high-ranking member of the South Side Compton Crips, and has confessed multiple times to involvement in the Tupac murder over the years.

Prosecutors also claim Keefe's made credible threats to witnesses while being locked up.

They also continue to claim they have mountains of evidence -- including Keefe D's own words -- pointing to Keefe orchestrating Tupac's murder back in 1996 ... despite Keefe now distancing himself from those previous statements.

The state's asking the court to keep him behind bars until his trial date ... and believes there are more than enough reasons to do so.
