In the place Where Great Britain used to be, there's a current push to ban knives, because someone might very well hurt themselves, and the Brits are going through a spot of "knife violence" with London overtaking New York in murders. Just like gun control, it's a wrong-headed focus on the tool rather than the criminal, continues the obsession of blaming crime on inanimate objects, and will likely give much the same results.
But, in their quest for a fully disarmed citizenry, the Essex police have stooped so low as to defame Cookie Monster and associate him with knives, violence, and cowardice.
To depict Cookie Monster in a picture under the title "Only Cowards Carry" depicts him as a craven coward associated with criminals that use knives, including Swiss army knives (yes, really), screwdrivers, and broken bottles is a most base insult.
Silly Brits, C is for cookie, not coward.
