The bullet-blasted Super Bowl celebration in Kansas City, which left one person dead and 20 others injured, has reopened the gun debate in both Missouri and Nebraska.

In question, so-called Constitutional Carry laws and the ‘good guy with a gun’ argument.

As we’ve reported, in 2022 Omaha police confiscated nearly 15 hundred 1,458 firearms, helped in part by a city law making the transportation of firearms illegal.

Now a new state law, so-called “Constitutional Carry” (LB77) ends that Omaha provision and several others.

Enter last week’s Super Bowl parade in Kansas City, bullets flying, hundreds of thousands running for their lives.

Witness: “You just hear pop, pop, pop, pop."

Kansas City, Missouri: Home to Constitutional Carry before Nebraska, when Omaha’s top cop told me this.

Police Chief Todd Schmaderer, Omaha: “There’s a half a million people in Omaha. It’s a population certainty that not everybody is going to be able to adjust to that new standard.”

But when lawmakers debated the bill, Schmaderer’s concerns were brushed aside, with one neighboring state put first and foremost.

State Sen. Tom Brewer: “Missouri has big cities so why our police would be unable to do the same quality work under the same conditions, Constitutional carry, as other states and other cities I do not know.”

Police Chief Todd Schmaderer, Omaha: “Look we're not looking to replicate Kansas City and Saint Louis. You can look at their statistics for crime compare them to Omaha and there is no comparison.”

Police Chief Stacey Graves, Kansas City: “We have subjects detained two of which are juveniles. We are working to determine the involvement of others and it should be noted we have recovered several firearms.”

And now two adults, two men, have been charged with second-degree murder and other felonies.

Prosecutors say Lyndell Mays got into an argument with an apparent stranger at the rally and pulled out a gun.

They say others did the same -- and bullets began flying.

One gun violence archive says this was at least the 48th mass shooting of the year.

Missouri Democrats are calling for increased safety regulations, while the state's Republican governor does not.

1:59 Gov. Mike Parson, Missouri (R):  "I don't think this is nothing, too new of a conversation for any of us when it comes about the gun laws. I mean, the same problem we're talking about today is the problem that was talked about a year, two years ago."

Sen. Brewer continues to stand by Constitutional Carry and tells me: “The shooting in Kansas City underscores the need for defenders to be prepared to defend themselves and others.”

That so-called ‘good guy with a gun’ theory, all but shot down by Schmaderer.

Joe Jordan, NCN: " Do you buy the good guy with the gun theory?"

Chief Schmaderer: I suppose there's some truth to it but there there's a tipping point too.

Jordan, NCN: "When officers show up at a scene and there is the "good guy" with the gun how do you know who the good guy is?"

Chief Schmaderer: "Well you don't always and obviously our approach to policing has to change because of that as well the probable cause standards are going to change. It used to be if you could address probable cause that somebody might have a gun you could make a stop and you could do a frisk and check for public safety needs with the onus that it's legal to have again you kind of lose that element of probable cause, so it alters our policing approach as well."
