Is that like butter?

 The BBC reports:

The idea of hospitals recording violent crime has now spread south of the border. One hospital in London has piloted the scheme and it will soon be extended across the capital, according to Det Chief Supt Chris McDonald, head of Operation Blunt, the knife cream taskforce at the Metropolitan Police.

Knife cream? Ew.

I can think of three possibilities:

• Bizarre typo for “crime”
• Allusion to the concept of “cream of the crop”
• Something I really don’t want to know about
