Plus lib voters who "feel good" vote knee-jerking progressive pinheads into office.

What about forks, butter knives, ballpoint pens, screwdrivers (both slotted and phillips), forks used for grilling, and a host of garden tools. Any of these can kill, so lets confiscate all of them, leaving the killers to figure out new ways (like the prisoners do in lockup). Liberal ideas as just so irrational

Clearly, they haven't seen the creativity of an American convict/inmate. They can fashion a very legitimate fighting instrument with ergonomic features out of a toothbrush and duct tape.

Yup. I've carried a Gerber Multitool with one hell of a sharp carbon-steel blade as one of the "tools" within for over 25 years, and I've never stabbed anyone with it.

Spitballs may still be in favor, as long as they are not the sticky type.

What happens when you have unrestricted borders and crap immigration laws.

Mockery is what me dino has been into every since I started this discussion.
You can't fix stupid.

Lotta people carry pocketknives because sometimes one comes in handy. Almost all of them have no intention of stabbing anyone.
I have a 32-year-old son who carries a pocketknife all the time and he hasn't stabbed anyone yet.
Heck, he's even a 9mm concealed carry like age 71 me. So far we've never gotten around to shooting anyone either.

Just so much insanity that I’m helpless to fix. I just have to mock it. Even that is becoming dangerous.

Me dino didn't either. That was just a spontaneous verbalization on my keyboard.
So on second thought, methinks the left would rather see kids just low tech throw rocks, since that would be more reminiscent of Antifa in riot mode. .

I actually like London. I go there on business. But for people who don't want to go, there's London. https://youtu.be/jn4gl1ZTfJY

"There is never a reason to carry a knife."
This just goes to show you can say "what does anyone need with X," where X is almost anything.

In apparently unintentional irony, the OP commentary says don't focus on the weapons used; focus on the criminals' physical appearance and group identity. It's as if to illustrate we cannot be satisfied with crime people illegal but not zero; we have to find someone's rights to take away.

Students throwing river rocks at a dangerous looking stranger was actually one of the alternative left solutions, against properly training and arming the school staff. Didn’t hear anything from the left about using sling shots.

Whoa! Why should students throw rocks when they can be propelled all the faster?
I suddenly recall a scene in a movie called Thinner when a young Gypsy woman shot a lead ball to make a hole through the protagonist's hand.
Hey, shooting lead balls. That's even better.
I've read that ancient slingers sometimes used lead balls instead of rounded river rocks way back when.
Lead balls. What does that remind me of?
Yes, the propulsion of lead balls.
Excuse me while me dino goes to go figure.

It has just occurred to me that ball point pens come with a safety mechanism, which is that button you can press with your thumb to retract the point.
Pencils ,on the other hand, cannot be rendered safe. I was a recruit on Parris Island when an hand-to-hand combat trainer said, "You can kill a man with a pencil. How?"
One recruit: "Sir! You can stick him in the eye. Sir!"
Trainer: "Yes the eye leads straight to the brain. Anyone else?"
Another recruit: "Sir! You can stick him in the ear. Sir!"
Trainer: "Yes, the ear canal also leads to the brain. Anyone else?"
Yet another recruit: "Sir! You can stick him in the throat. Sir!"
Trainer: "Yes, and try to sever the carotid artery. Heck you can even shove it down his throat. The point I'm trying to make is that there's all kinds of objects~bla,bla, etc."
Remember when Heath Ledger's Joker made a pencil disappear? Grabbed a Gotham City hood by the head and slammed him face-down on a pencil balanced on it brand new eraser. Right through the old eye socket that pencil went to indeed disappear. Wow, what a magic act that was.
Maybe I should sit down and send a note right over to Mayor Kahn to advise him of the pencils not coming with a safety mechanism.
On the other hand, nah! My keyboard might try to hit me.

With the proper permit, perfectly legal. Rocks however are heavily taxed. There are exemptions for buckets of river rocks used for authorized student stoning of strangers.

Slingshots must still be legal, ah, until further notice.

So now they can't even bring a knife to a gun fight..the Brits are starting to give a whole new perception to derogatory term"bambi".

Latter...
Why focus on the cause of these increased pen stabbings? All we need to do is ask how can we all make all the ball point pens safer? And, how can we get white males to surrender all those unsafe ball point pens?
