Knife crime and Gun crime do not just concern murder.

Carrying a gun, or a knife in public are both crimes regardless of murder.

Chatting up girls on the street is not grooming unless the intent is to entrap them and rape them as it then becomes the means by which the rape is enabled.

So while gun crime and knife crime can exist independantly of murder, street grooming cannot exist independantly of rape, whether statutory or other.

It would be an unprosecutable law as it woud be impossible to determine a players motives until after the fact.

Giving lifts and chatting to girls in shopping centres etc are not crimes.
