Philadelphia officials are caught in the middle of a wave of gun violence in their city. Nearly two dozen shootings happened in the city over the last weekend alone and four people were left dead. Another 15 were wounded.

It’s far from the only city where such developments are being reported amid of series of anti-police moves by Black Lives Matter and others in recent weeks. Some places are “defunding” police, other places officers are just being attacked and maligned.

But it appears that Philadelphia, so far, is the only city to pursue this solution: Having law-abiding gun owners turn in weapons to crack down on gun use by criminals.

According to a report in BizPacReview, the “Home Gun-Check Campaign” was launched over the weekend.

It’s not a buyback program, which has happened in other cities.

It’s a turn-it-in campaign.

“Get those guns, run in that room, see what’s in there, find out what is being hidden in your house, take it out and turn it in,” City Councilmember Cindy Bass told a news conference.

“Are people really this dumb?” openly wondered President Donald Trump’s son.
