Guns are back at the Legislature, as Nebraskans testify to state lawmakers.Law enforcement and civilians are speaking for and against a bill that would allow permitless concealed carry across the state. State Sen. Tom Brewer, of Gordon, proposes LB77 — a proposed law that's lived and died since 2017.The last time the bill was brought to the legislature, gun owners brought their weapons to the Capitol to prove a point, but the bill eventually failed.Brewer asked proponents to leave their guns at home this time around, hoping a milder approach to the legislation will help get it passed.But it's a battle in the metro areas like Lincoln and Omaha.Omaha police Chief Todd Schmaderer opposes permitless concealed carry in Nebraska. "It's a bill that did not take into account local control," Schmaderer said.He's concerned about how the bill would eliminate two ordinances in cities like Omaha."When you look at Omaha, we have a few ordinances in place that help us address violent crime in our city, help us address gun violence," Schmaderer said. "I am concerned about the loopholes and some of the unintended consequences of LB77, as it will affect Omaha."Schmaderer said LB77 would eliminate the city's gun registration ordinance — something he said plays a role in how the department addresses violent crime: "The ordinance helps us prevent the mentally ill, substance abusers, gang members and known criminals from purchasing a firearm."The chief and Douglas County sheriff said they support law-abiding citizens but that LB77 negatively impacts our part of the state. "It'll eliminate our current ability to charge serious misdemeanor offenders with a standalone gun crime. Ultimately, that can escalate into a felony," Douglas County Sheriff Aaron Hanson said.Nebraskans came from far and wide to support the bill, whiles others recounted mass shootings across the country.Two dozen lawmakers co-sponsor Brewer's bill."Let's get this to a bill we can move forward with and not go down a patch we've gone through before," Brewer said. Brewer said people in his district support the bill and that the attorney general is OK with it — he added that other states surrounding Nebraska have similar laws. Supporters said the bill is something fundamentally guaranteed by the second amendment, and any restrictions, like requiring a permit, are infringing on that right.But some people said they're concerned about background checks, and domestic violence situations. One woman said this isn't the kind of gun discussion the legislature should be having."Instead of conversations to ensure continued gun safety measures, we're discussing the elimination of them," she said. With no vote Thursday, it's another contested bill in the early stages.Top headlines:Fremont elementary student brought gun to school, thought it was a 'toy'Omaha police investigating armed robbery at First National Bank Omaha police allege teen tried to light women, infant on fire
