Some Beverly Hills police officers aren't happy Eric And Lyle Menendez could potentially be released… and some officials are even going so far as to condemn it as a political move.

Law enforcement sources tell TMZ … several officers from the Beverly Hills Police Department – the city where the murders took place – say the Los Angeles County district attorney George Gascon tries to win political points by letting the brothers out of prison.

He has fallen behind his competitor in the polls, Nathan Hochmanand some officials see it as a big step toward getting back into the race.

It's not that the police don't necessarily believe the brothers' claims about their father Jose They abused her, our sources say… They just don't believe that justifies the brutal shotgun murders of her parents.

We were also told that many BHPD officers were not on duty when the murders occurred, so they do not know or care about the case as well as older veterans.

However, we are told that the police officers with knowledge of the case stand by their previous investigation… and say they have done their job and this is now the prosecutor's matter.

In just a few hours it will be DA will announce it whether he will try to free the brothers. Gascón could go two ways – either ask a judge to convict Erik and Lyle, or ask the judge to overturn the murder conviction and impose a voluntary manslaughter conviction.

The maximum sentence for involuntary manslaughter in Cali is 11 years, and the brothers have served almost 35 years… so if the judge signs, they would be released. He will announce his decision during a press conference scheduled for 1:30 p.m. PT.
