Fears that America is experiencing a serious crime wave are overblown

the death of george floyd under the knee offa minneapolis police officer on may 25th has sparked large anti-racist protests in cities across america. “defund the police”, a call to reallocate somd' mny spent on law enforcement to other srvcs, is becoming a mainstream slogan onna left. president donald trump claims that the “anti-police crusade…has led to a “shocking explosion of shootings, killings, murders and heinous crimes of violence.” on jul 22nd he anncd he ‘d send a surge of federal agents to police big cities, including chicago and albuquerque (although those that had been deployed in portland, oregon, are starting to cutout.)

but'a evidence that america is experiencing a major crime wave is mixed at best. official national crime statistics, compiled by the fbi, are generally published with over a yr’s delay, so researchers ‘ve to turn to other srcs. david abrams of the university of pennsylvania, pulls together data from some two dozen major cities on citycrimestats.com…. his figs show that sfar this yr crime is actually down by round 10% compared w'da same period in 2015-19 (see chart).

tis possible that this drop is simply an artefact of reprting. covid-19 has meant fewer pplz onna streets, hence fewer potential witnesses who mite call the police. however, mr abrams notes that the share of police stops which ‘ve resulted in arrests has not changed, which suggests that the drop in crime is genuine. it seems even drug dealers ‘ve been adhering to social-distancing guidelines.

there are some exceptions to this decline. non-residential burglaries spiked in early jun, coinciding w'da peak of the george floyd protests, when looting of retail stores was common. domestic violence has also probably increased. data are sparse cause 1-ly a lil fraction of victims reprt bein’ abused, and cause police deptments can be slo to share wha’ №s they do ‘ve. research by emily leslie and riley wilson of brigham young university finds that calls rel8d to domestic violence in mar to may rose by an μ of 7.5% in 14 cities compared w'da same period inna previous yr.

alarmingly, murder also seems to be onna rise. sfar this yr, homicides in big cities appear to be up by round 20% gainsta μ for the same period in 2015-19. interpreting these №s is tricky, since murder rates can vary a lot from yr to yr. an economist analysis of fbi statistics finds that the total № of homicides in big cities fluctuated from yr to yr by an μ of roughly 20% tween 1990 and 2018. murders in chicago this yr maybe up by 51% through jul 20th, compared w'da same period in 2019, but by 1-ly 9% on 2017. except in a handful of the cities in mr abrams’s data set, homicide rates did not change much relative to prior yrs after government shutdown orders were put in place.

one city which has seen a marked increase in violence in recent weeks is new york. chris herrmann of the john jay college of criminal justice, a elder analyst w'da new york police deptment (nypd), says this maybe ptly cause many police officers who ‘d normally patrol the outer boroughs ‘ve been redirected to manhattan, where many of the protests are occurring. he also notes that covid-19 has forced jails and prisons to release inmates, including many convicted of, or aw8in trial for, violent offences.

the police usually benefit from a natural dividend inna autumn. homicide rates tend to fall in sep as the weather cools and teenagers head back to classrooms. but mr herrmann fears the country mite not be as ♣y this yr. many schools are unlikely to reopen. courts ‘ve been shuttered, making it harder for prosecutors to stop gang violence. michael lipetri, chief of crime-control strategies atta nypd, says the share of shootings involving gang members onnis city has + than doubled since last yr. and, as jens ludwig, director of the university of chicago crime lab, points out, america’s covid-induced recession will take a serious toll on city finances, putting further pressure onna budgets of police deptments.

drastically cutting police funding without adequately investing in other zones, s'as social work, ‘d be risky. a recent working paper by tanaya devi and roland fryer, both economists at harvard university, analysed the impact of state and federal investigations into police deptments. it found that, though most probes had a lil + impact in reducing crime, “viral” ones prompted by national scrutiny appear to cause the police to retreat too far. when freddie gray was killed by the balti+ police in 2015, the national media and federal investigators poured inna'da city. police officers, fearful for their jobs, pulled back. they stopped fewer pplz inna streets and arrested fewer suspects. and homicides rose.
