For four nights, speakers at the Republican National Convention pilloried Democrat Joe Biden over his alleged weakness on crime and painted a dystopian future if he were to be elected in November.

Biden and Democrats were "completely silent about the rioters and criminals spreading mayhem in Democrat-run cities," during their convention, President Trump charged on Thursday. The previous evening, Vice President Pence warned, "The hard truth is you will not be safe in Joe Biden's America."

The speeches came as residents of Kenosha, Wis., were reeling from the shooting by police of Jacob Blake, a 29-year-old Black man, and the resulting protests — during which two people were fatally shot. The unrest follows turmoil in other cities after police killed George Floyd, also a Black man, in Minneapolis in May.

Pence claimed that Biden would "double down in the very policies that are leading to violence in American cites," to which Biden responded with a reminder that "right now ... we're in Donald Trump's America."

The current crime rate

Statistics show that some crime has been increasing in big cities, with mayors who are Democrats and Republicans. According to figures compiled by data analyst and consultant Jeff Asher, the murder rate this year has increased by 26% through July, compared with a year ago. Other violent crimes are up slightly, while property crimes are down by 7.7%.

This is a reversal of longer-term trends, in which violent crimes have been generally declining since the 1990s.

In an email, Asher says determining the cause for the increase this year is complicated.

"We barely have the data to recognize that a new trend is occurring, much less to be able to properly evaluate and diagnose its cause," he says. But the "intense stresses being placed on numerous aspects of society by the pandemic is as persuasive as any."

Trump's record

The Trump administration announced this summer that it was sending federal resources to cities, including additional FBI agents, along with U.S. marshals and agents from the Drug Enforcement Administration and the Bureau of Alcohol, Tobacco, Firearms and Explosives, to — in the Justice Department's words — "fight the sudden surge of violent crime."

But Trump — who promised in his 2016 acceptance speech that "the crime and violence that today afflicts our nation will soon, and I mean very soon, come to an end" — has a spotty record when it comes to criminal justice reform.

His signature achievement on the issue, the widely touted First Step Act, signed in 2018 and passed with bipartisan support in Congress, instituted sentencing reforms, including reducing harsh penalties for crack cocaine possession. And on Friday, Trump pardoned Alice Johnson, a criminal justice reform advocate who delivered a powerful address at the Republican National Convention this week and whose cause had been espoused by Kim Kardashian West. But some parts of the law have fallen short, activists say.

In June, following the unrest after Floyd's killing, Trump signed an executive order that would provide federal grants to improve police training and create a national database of police misconduct complaints. But it fell well short of what activists say is needed.

Congress was unable to reconcile police reform proposals earlier this summer.

Biden's record

As Republicans were fond of noting during their convention, Biden has a 47-year record as a U.S. senator and then vice president. During much of his Senate career, he was a member of and chairman of the Judiciary Committee and in 1994 sponsored the Violent Crime Control and Law Enforcement Act.

It came in a different era, as Democrats set out to prove that they, too, were "tough on crime." The bill included a 10-year ban on assault-style weapons as well as the Violence Against Women Act, which Biden points to today as a signal of his commitment to ending domestic violence.

But the act also included harsh penalties for drug-related crimes and money to construct new prisons, which critics said led to the mass incarceration of Black men. It also included funding to hire 100,000 additional police officers.

Now, Biden has backed away from some of the provisions in that bill, while at the same time rejecting calls by some in his party to defund police departments.

He has proposed a ban on police chokeholds, a new federal police oversight commission, new national standards for when and how police use force, more mandatory data collection from local law enforcement and other steps.

Former prosecutor Kamala Harris

Biden's running mate, Sen. Kamala Harris, brings her own record on criminal justice issues to the Democratic ticket. She was San Francisco's district attorney and then California's attorney general before her election to the Senate.

As district attorney, she initiated a policy for first-time drug offenders to get a high school diploma and a job instead of prison.

As attorney general, she refused to seek the death penalty for a man who killed a police officer. She also instituted a controversial policy that threatened to prosecute parents of children who skipped school as a way to reduce truancy.

She told NPR's Morning Edition in March, when she was still running for president in the Democratic primary, that "nobody went to jail, and hundreds and hundreds and hundreds of families went through our program, which was a program of getting greater resources to them so the child could be in school every day."

In the Senate, she co-sponsored with Republican Sen. Rand Paul a bail reform measure as a way of reducing the number of people held, arguing in a 2017 New York Times op-ed with Rand that "excessive bail disproportionately harms people from low-income communities and communities of color."
