In an ongoing series, drawing to your attention solutions to problems that don't exist, we bring you Exhibit 135896347218652347985:
US schools have a mandatory "zero tolerance" on possession of weapons on school grounds - expulsion or long term suspension is the punishment, even if the weapon is being brandished by a six year old boy showing-off his boy scout utility implement, (verdict pending) or a seven year old girl using a knife to cut out house windows in a paper creation (one year suspension).
Mass injuries by knife are not exactly a common occurrence, even in the US.
Of the hundreds of school children killed in the US each year, almost all are shot dead - same method used in mass killings.
It's a fork, it's a spoon ... it's a weapon?
