Hundreds of police officers from six forces - including Sussex and Thames Valley - are taking part in a pilot exercise to improve stop-and-search techniques.
It follows the death of 15-year-old Alan Cartwright, who was stabbed to death. His family are calling for more police stop and searches to curb knife crime.
The initiative by the College of Policing involves more than 1,300 officers from the Metropolitan Police Service, Cleveland, Sussex, Thames Valley and Greater Manchester forces, and the British Transport Police.
About 220 officers from each were chosen to take part in the pilot, which was designed with the Equality and Human Rights Commission (ERHRC).
The impact of the training will be analysed by the college and independent researchers to establish if the training changes the way officers approach stop and search.
"We know the public supports the police use of stop and search powers especially where the powers are used to keep people safe. The challenge now is to make stop and searches more effective because high numbers of negative searches can help to create a view that they are unfair and constitute a disproportionate response from police.
"The training will help officers to recognise unconscious bias and monitor how they make decisions about the use of stop and search powers."
Commuters in the Thames Valley have long complained of severe overcrowding on the trains.
But that could be about to change. First Great Western says it has listened - and in a radical move the rail operator is to rip out most of its first class carriages.
That should provide an extra 3,500 seats a week. Our Transport Correspondent Mike Pearse reports.
Hundreds of people have attended the annual Thames Valley Police open day in Berkshire.
The event was opened by the Chief Constable and is an opportunity for the public to get to know a bit more about police work.
Richard Slee reports.
Thames Valley Police are preparing their operation for policing Royal Ascot which begins next week Tuesday.
The force says a "significant security operation" will be in place during the five-day event which will be attended by the Queen and other members of the royal family.
"Thames Valley Police has been involved in policing Royal Ascot for many years. Every year is different but the challenge remains the same for us to support those attending as well as those living near to Ascot Racecourse.
"The event attracts a global audience and thousands of prestigious visitors but our planning and approach is no different to any other large scale public operation.
"A great many officers and staff have been working on the plans in partnership with Ascot Racecourse Limited, the Royal Borough of Windsor and Maidenhead and neighbouring police forces. We anticipate the focus remaining firmly on the track but will remain ready to respond if required."

From next year there will be trains with twelve carriages which will be some the longest in the country all over the Thames Valley. It will mean up to 25 per cent more rush hour seats in Berkshire, Hampshire, Oxfordshire and Surrey.
It is part of a major upgrade that will see almost 60 new and refurbished carriages on local routes.
There will also be two new evening peak rail services from Paddington to Maidenhead, adding over 350 seats for passengers.
A new Monday to Friday 16:42 London Paddington to Bourne End (17:24) service will call at Maidenhead (17:11) and plug an hour gap in services from Maidenhead between 16:47 and 17:47 with a 17:12 departure. The service will also call at Furze Platt and Cookham.
This will be supplemented with a new 19:36 London Paddington to Twyford (20:07) service, calling at Maidenhead at 20:00.
The additional services will come into effect with First Great Western’s summer timetable, starting on Monday 18th May, increasing capacity on London Thames Valley services prior to the introduction of Electric Multiple Unit trains during 2016.
In the Thames Valley, First Great Western will replace most of its Turbo commuter fleet with a mix of 58 electric trains comprised of 37 new and as-new four-carriage Class 387 trains and 21 four-carriage Class 365 trains from spring 2016. This will increase the number of seats for commuters travelling in the high peak by 25% from 2017. These new trains can run with up to 12 coaches.
