Police in England and Wales are now given greater powers to stop and search for solutions is growing knife crime.
Interior Minister Sajida Zhavid makes it easier for officers to search people without reasonable suspicion in those places where it can occur sur & # 39; oznae violence.
It comes after a fatal scabies grew last year to its highest level since the beginning of the recording.
Fighters said the move was "disappointing and regressive" and that the stop and search "has no effect".
Stop and search powers have been controversial for many years, with proof that they are often wrong, and that they are focused on black people disproportionately.
But Mr Zhavid said. "The police on the front lines in the fight against the suras & # 39; oznaga violence and it is important we give them the right tools to do their job"
Change is currently being tested in seven districts of the police forces, where there is more than 60% of knife crime in London, the West Midlands, Merseyside, South Yorkshire, West Yorkshire, South Wales and Greater Manchester.
This makes it easier to use the so-called "section 60" searches where employees can find someone in a particular area for a limited period of time to prevent violent crimes
In accordance with the new rules, the inspectors will be able to authorize the use of section 60; Currently, more senior officials must agree.
There will also be below the threshold for authorization requests – Police only base it will be necessary to assume sur & # 39; oznae violence "may" happen, not that it "will."
Section 60 has been used for large events such as the Notting Hill Carnival last year after violent incidents, such as stabbing a man outside Clapham metro station on Friday.
Other forces that make up the majority of requests will remain the same and will continue to require officers to have reasonable suspicion of a crime.
With 285 deaths from stab wounds in 2017-18, the most ever recorded, and a wave of high-profile murders this year, the ministers have come under increasing pressure to solve crimes knife.
Metropolitan Police Commissioner Cressida Dick said officers in London increased use of section 60 in the last 18 months, after 132 deaths from stab wounds in the capital during 2017-18.
She said: "Stop and search with & # 39 is a very important force for the police This is undoubtedly a & # 39 is part of our growing results suppress the levels of violence and knife crime .."
But Katrina French, Chief Executive StopWatch, that the campaign against the excessive use of stop and search, said: "This decision is a & # 39 is a disappointment and a regressive move, the policy does not save lives."
Eliminating the need for reasonable suspicion "is not only exacerbate racial disparities, but have the potential to further damage the relationship between the black community and the police," she said.
The study looked for the police college for ten years to stop and search data in London, and found it to be "inconsistent" and "weak" as a deterrent.
To reduce levels of violent crime by 2% in the region over the next week, the police will have to spend up to 200 times the number of weapons searches, he said.
Additional authority to roll back key changes made by the prime minister's & # 39; MINISTER Theresa May 2014, when she was home secretary.
She introduced a revised code of conduct after the investigation examined thousands of searches and found 27% may have been illegal.
If used incorrectly, a stop and search has been a "huge waste of police time" and "unacceptable insult to justice," she said.
Speaking about the recent report, the prime minister's & # 39; er-minister said that the powers were "an important tool in the fight against knife crime."
Partly as a result of the 2014 changes, the use of stop and search has fallen in England and Wales from the peak of 1.4 million a decade ago to 277.378 last year.
The number of requests has fallen for each ethnic group, but ethnic and racial inequality has increased. In 2014-15 black people were four times more likely to look like white people, while in 2017-18, they were 9.5 times more likely to search for.
