President Joe Biden speaks during an event in the State Dining room of the White House in Washington, Wednesday, June 23, 2021, to discuss gun crime prevention strategy.

WASHINGTON — President Joe Biden announced new efforts Wednesday to stem a rising national tide of violent crime, declaring the federal government is “taking on the bad actors doing bad things to our communities.” But questions persist about how effective the efforts can be in what could be a turbulent summer.

Crime rates have risen after plummeting during the initial months of the coronavirus pandemic, creating economic hardship and anxiety. Biden's plan focuses on providing money to cities that need more police, offering community support and most of all cracking down on gun violence and those supplying illegal firearms.

“These merchants of death are breaking the law for profit,” Biden said. “If you willfully sell a gun to someone who's prohibited, my message to you is this: We'll find you and we'll seek your license to sell guns. We'll make sure you can't sell death and mayhem on our streets.”

But there are also tricky politics at play, and Biden's plan shows how few options the Democratic president has on the issue.

The steps he outlined are aimed at going hard after gun dealers who break federal law and establishing strike forces in several cities to help stop weapons trafficking. He also said he would seek more money for the agency that tracks the nation's guns.

But the rest of his new strategy boils down mostly to suggestions for beleaguered localities. He's encouraging cities to invest some of their COVID-19 relief funds into policing and pushing alternative crime reduction steps such as increased community support and summer jobs for teenagers — often both targets and perpetrators of violence.

But it's voluntary.

Biden announced a “zero tolerance” policy that would give no leeway to gun dealers who fail to comply with federal law — their licenses to sell would be revoked on a first offense.
