Details of Merseyside police's decision to release the suspect's race in a collision with the Liverpool parade could cause "difficulties and challenges" for future troops, a former principal said.

Merseyside police said they arrested a 53-year-old white British man about two hours after the incident, which caused dozens of people, including four children, injured.

Dal Babu, a senior Metropolitan official, told the Guardian's first edition that the decision was "unprecedented", but he could envision putting pressure on the troops in the future to release details about the suspect's racial background.

"Rocket science doesn't need to predict what will happen: Too big rights will distort that and say, 'Yes, you're because this is a white man. Why don't you name the next person?" He said that it will bring some difficulties and challenges to the police. ”

Babu stressed that the decision was “right” and could share “misinformation of racism and Islamophobia” on social media, while warning that every decision should be made on case-by-case basis.

“You can imagine what the far right would say, ‘Oh, you didn’t name this person’s race, that’s because they are people of color.”

"It is very important for people not to regard it as a precedent because every event will be different. People may feel in future events that have the right to know race and race, and it may not be appropriate to release it."

A senior legal source said that in some cases, the race that named the suspects could cause riots rather than calm them down.

"If they arrest someone in a recent boat ride or similar situation with obvious Muslim names, they will be under tremendous pressure," the source said.

The Guardian was told that extreme extremists used social media to exploit horror scenes within minutes of the Liverpool tragedy.

An account claimed the incident was a terrorist attack.

Another account also made false claims, including what the police said, and the person arrested by the police at the scene was indeed a Muslim.

Last summer, Morsiside police were criticized for not posting more information after launching the rumor that the killer was a Muslim asylum seeker online after the Southport murder occurred.

For Merseyside police, the decision to release details on the suspect’s race and nationality on Monday night is not a precedent.

A source said a source said a source said a source said a detective convinced the detained suspect was the only person they wanted, a source said. This may be wrong in the case where the suspect’s identity is unclear and that identity may be a problem at trial.

In March, Chief Police Officer Serena Kennedy told MPs she wanted to remove false information after the Southport murder by publishing information about the religion of the assailant Axel Rudakubana, because he came from a Christian family but was informed by local royal prosecutors.

Police did reveal that the suspect was a 17-year-old male from a bank in Lancashire and was born in Cardiff.

There have been widespread riots in the murders, with some illnesses targeting mosques and hotel housing asylum seekers.

Jonathan Hall KC, the government's official terrorism legislative examiner, told the Guardian that Merseyside's decision on Monday night should set a precedent for future events.

“The authorities seem to have learned Southport’s lessons.

"This should be a precedent, while recognizing the odd number that you have to say little or nothing. Transparency is the right precedent."

Hall said if the suspect in a high-profile case is a Muslim asylum seeker: "You have to do that, too."

Nick Lowles’ hope is not hate Nick Lowles, a leading group that monitors the far right, said: “The police learned their lessons after Southport. What they did this time is to fill the gaps and delete the information as soon as possible.

“If that was a terrorist attack, I’m not sure if it would intensify tensions.”

White Hall sources said the decision to release details was an operational issue and therefore separate from the government.

Asked if he would like to release similar details in similar situations in the future, Prime Minister Keir Starmer said: “It’s the police’s business and the investigation is underway, so I think we need to leave it to them.

“I think today is really about thinking about all the people affected by this and definitely knowing that we are standing with them.”
