I'm a bit confused by this. I thought there was a news report saying that someone had already been apprehended for the murder of the two women, but just now on the news I think they said the search continues.
When there is evidence of corruption, discrimination or negligence should we say "they get it right more often than they get it wrong". That may well be the case, but when we are talking about people who are supposed to be upholding the rule of law it is especially important that they are seen to act within the law too and apply the law equally to everyone. Even if the vast majority of lawyers, doctors, nurses, police officers, etc, etc, behave impeccably, that does not minimise the need for effective action to be taken against those who do not - and further training undertaken where necessary.
When incidents such as the following happen, it is quite understandable that there is continuing concern about racism (whether conscious or unconscious) in the police:

Guardian June 2020
"Huugo Boateng was taking part in a charity bike ride with his father along the River Lea in north London when he says he was grabbed from his bike by a plainclothes police officer, threatened with a stun gun and fell face first into thorny bushes.
"The 13-year-old told the Observer: “I’d turned around to see if my dad had caught up behind me, and suddenly this man came out of nowhere. He was crazy angry and shouting. I got scared because I thought he might be mugging me or trying to give me corona so I ran, but there was nowhere to go but in the bushes.”
"While he was down on the ground, the teenager says the officer pointed a Taser at him and threatened to shoot. The officer then arrested Huugo and put him in handcuffs. Further down the towpath, his father, Andrew, 43, was told to get on his knees and put his hands behind his back. Andrew was also handcuffed. The two were detained, suspected to have been involved in a stabbing in the area.
...." Huugo suffered lacerations to his face and bruises on his legs, and spent that night sleeping on his parents’ bedroom floor, anxious not to be alone.
...................."The officers said they were responding to a stabbing in a nearby park
The arrests were partly filmed by river boat resident and photographer, Louise Paton who had responded to Andrew’s pleas for someone to film what was going on. She described the scene as:
“racial profiling at its worst. The mood was defensive, borderline aggressive and patronising,” she said. “I was disgusted. It really drove the issue [of racism] home for me. The way they spoke to Andrew, the way they treated him and kept him in handcuffs so long when he could prove so quickly he was completely innocent and the wrong person. It was just so disappointing to see.”
"The family were visited by a community officer later that evening. “Huugo didn’t want them to come in so they stayed on the doorstep and asked if we were OK,” said Andrew, who works at City University. He is also active in local projects including coaching a youth football team and volunteering for the outreach programme Kickoff@3 , which is co-run by a black Metropolitan police officer, Michael Wallace.
“I couldn’t vouch for a more humble and more dedicated member of the community,” said Wallace. “The irony is that Kickoff@3 is about building good relationships with youth and the police, and Andy is instrumental in helping with that programme. The bike ride he was doing was organised by us – we were raising money for a homeless charity and a domestic violence one.”
This incident is widely reported in other papers but the Guardian has a video link of the footage taken by Ms Paton.
