Those mass shootings were outliers, and yet other mass killings have continued to happen, in fact have increased because the victims didn't have any means to stop the attackers. Firearms there USED TO BE the great equalizer. Moreover, gun crimes over there were generally declining anyway. Funny thing is, there are STILL gun crimes that happen there but the media won't report them, because that would ruin their narrative. The criminals simply bring theirs in from elsewhere.
There ARE in fact mass knife attacks happening there, but again that's not being reported because the killers are mudslimes (muslims, for you politically correct types)... and as for your last statement, well that's so false and outlandish I just can't stop LMAO that I'll just leave it there.
