Why were these people employed in the first place and allowed to keep their job if convicted after being employed?
Serving Met Police officers have been taken away from tackling serious crime and terrorism and instead told to investigate wrongdoing in the force.
Commissioner Sir Mark Rowley said about 90 officers had been moved away from fighting serious and organised crime to the Met's professional standards team.
He has said there are hundreds who should not be in the force.
It comes after the force was branded as institutionally racist, homophobic and misogynistic in a damning report.
In an open letter to the Mayor of London and Home Secretary Suella Braverman, Sir Mark said officers had been diverted to the force's Directorate of Professional Standards (DPS).
According to his findings, four in five of the original inquiries into officers accused of domestic and sexual violence in the last decade did not result in the correct action and should be reassessed.
"Not only have we increased our DPS by 150 people, but the scale and urgency of this work has meant diverting officers from other missions such as serious and organised crime and counter-terrorism," he wrote.
"Over the last three months we have had, on average, 90 additional officers and staff from these areas supporting DPS." Many had volunteered, he added.
Sir Mark's letter updated the Met's efforts to weed out rogue officers. Vetting rules have been tightened, and in the next six months about 100 officers will have their status reviewed and "may well end up leaving the organisation", Sir Mark told BBC News.
He said it was the first step in "the biggest drive on professional standards in the Metropolitan Police in 50 years".
"We have hundreds of people who shouldn't be here and the tens of thousands of good men and women here are as embarrassed and angered by that as anybody, and they're helping us sort them out," he added.
Sir Mark has previously said he was considering banning anyone with convictions, other than the most minor, from the force.
He told BBC Radio 4's Today programme that the current policy on accepting staff was "too permissive" and left "too much ground for interpretation".
He added that "byzantine and complex" police regulations mean that some officers under investigation have already been sacked by the Met, but were then reinstated by an independent lawyer.
"Listeners will be surprised to know that the commissioner doesn't have a final say who is in his or her organisation," he told the programme.
The move follows the murder of Sarah Everard by Met Police officer Wayne Couzens and the jailing of serial rapist and disgraced officer David Carrick.
A poll commissioned by BBC London found public confidence in the Met Police has been shattered.
Out of more than 1000 people surveyed, almost half of female respondents surveyed said they "totally distrusted" the Met following numerous controversies involving some of its officers.
