Gov. Josh Green today signed into law several bills he said will give police and prosecutors the tools they need to “put in jail for a very, very long time” those who kill or injure others with illegal fireworks.

Green praised legislators for “stepping up, big time” in the wake of a fireworks explosion this past New Year’s Eve in the Aliamanu neighborhood of Honolulu that killed six people and injured about 20 others.

“It was a complete tragedy,” said Green. “The explosions that occurred because of the fireworks … should never have happened. And it’s because we as a society haven’t done enough to be safe.”

The Aliamanu calamity occurred when a “cake” containing about 50 lit aerial fireworks tipped over and ignited other fireworks in nearby crates.

House Bill 1483 sets progressively harsher penalties depending on the scope of the offense.

Under the new law, illegally setting off aerials within 500 feet of a house or hotel is now a misdemeanor, punishable by up to a year jail and/or a fine of up to $2,000.

If the offender has a prior fireworks conviction in the past decade, that offense becomes a Class C felony, punishable by up to five years in prison.

If a person suffers a substantial injury as a result of those fireworks, the offense becomes a Class B felony, punishable by up to 10 years imprisonment.

And if a victim suffers life-threatening injury or death, the offense rises to a Class A felony, punishable by up to 20 years behind bars.

“The police are going to be able to charge and have the prosecutors prosecute cases to the max because of what the Legislature did,” Green said. “And these penalties are not going to be small. If a firework goes off, and you have it illegally, and it blows somebody up? Honestly, you’re going to go to jail for 20 years.”

The legislation was introduced by Rep. Scot Matayoshi, a Windward Oahu Democrat, with co-signers including Big Island Reps. Greggor Ilagan, Matthias Kusch, Nicole Lowen and David Tarnas, all Democrats.

Supporters include: state Attorney General Anne Lopez; the state Department of Law Enforcement; Hawaii Police Department Chief Benjamin Moszkowicz; Hawaii Fire Department Chief Kazuo Todd, who’s chairman of the Hawaii State Fire Council; the Honolulu Police Department; Honolulu Fire Chief Sheldon Hao; Maui County Prosecutor Andrew Martin; Maui County Fire Chief Bradford Ventura; and the Hawaiian Humane Society.

Testimony in opposition was submitted by the state Office of the Public Defender, retailers Phantom Fireworks and TNT Fireworks, and the Libertarian Party of Hawaii.

Another measure signed by Green, House Bill 550, authorizes law enforcement agencies to use video and photographs gathered by drones as probable cause for arrests and charges if the unmanned aerial vehicle is recording directly above public property and the act leading to the arrest is committed on public property, such as a park or public street.

The measure was introduced by Rep. Cory Chun, an Oahu Democrat. Co-signers include Lowen and Rep. Chris Todd, a Hilo Democrat.

Department of Law Enforcement Director Mike Lambert called the use of drones to collect evidence of prosecution “a huge advantage for law enforcement agencies across the state” and credited Green and lawmakers for “giving us the laws and tools to truly make a difference moving forward.”

Supporters of the bill include the Honolulu Police Department, the DLE and the Hawaiian Humane Society.

Opponents include the Office of the Public Defender and the Libertarian Party of Hawaii.

Other fireworks-related bills signed into law include:

— HB 806, which appropriates $1 million for the fiscal biennium to conduct covert fireworks sting operations and $2 million for an explosives and fireworks laboratory on Oahu. The measure was introduced by Rep. Scot Matayoshi, an Oahu Democrat. Co-signers include Lowen, Tarnas and Todd.

— SB 222, which extends the sunset date of the Illegal Fireworks Task Force from today to June 30, 2030, and extends the annual reporting requirements to the Legislature. It was introduced by Sen. Brandon Elefante, an Oahu Democrat, with co-signers including Big Island Sens. Tim Richards and Joy San Buenaventura, both Democrats.

“This legislative session saw a fierce and determined push to advance meaningful firework legislation aimed at preventing future tragedies,” said Green, who mentioned both Aliamanu and the possibility of a wildfire caused by pyrotechnics. “These bills are commendable and reflect the collaborative efforts of community leaders, first responders and lawmakers who made possible these long-awaited changes to enhance public safety.”

All of the measures became law upon Green’s signature.
