A Conservative MP suggested that people "prepare" to better defend themselves and survive a knife attack.
Sir Christopher Chope asked senior police chiefs to agree with his idea of "further encouraging" young people to embark on martial arts.
He described the plan to strengthen the teaching of judo and taekwondo as "alternative", just like women who learn "to cope with violent men".
Dave Thompson, chief police officer of the West Midlands Police, rejected the idea of a national strategy to improve "street fighting skills", but admitted that "it does something different.
In 2019, a series of deadly stab wounds were perpetrated throughout the United Kingdom, along with cuts in the country's police force.
Sir Christopher told Thompson in front of the House of Commons Selecting Committee: "One of the ways to get ready is, for example, judo, taekwondo, physical ability and management of the situation threatened with a knife.
"Do you think there is anything to be said for increasing the encouragement of young people so that they do not have to pull out a knife?"
"They can protect themselves by really knowing how to handle such an incident, if any."
Mr. Thompson told him that the best prevention against knives was to "run away as fast as possible".
Sir Christopher added that "you must be able to do that", leading the West Midlands police chief to warn, "I think people have to flee.
"I probably had not advocated a strategy of increasing the readiness for combat and martial arts of young people in general."
He added that some martial arts are "extremely popular" and "take young men off the street".
Sir Christopher replied that it was "an alternative".
"So, they say," I'm wearing a knife because I want to protect myself, "an alternative to that is actually to protect yourself by being in better shape and more able to cope with that kind of thing. attack, "he said.
"In the same way that many young women learn to deal with men who are violent or threatening to them."
Cressida Dick, Commissioner of the Metropolitan Police, said that a "meaningful and useful activity is always a good thing" and that sports programs "obviously protect young people in a very safe way".
"I do not reject your argument," she insisted.
