An Iowa State University study has found when bar and nightclub owners increase  security, they can help reduce crime for a neighborhood.

Kyle Burgason, an assistant professor of sociology at Iowa State University, said: “We found that within a half block of these bars there was an increased risk, in some cases up to 500 times greater risk, to be exposed to violent crime.”

Burgason studied violent crime surrounding “private” bars and nightclubs when he lived in Little Rock, Arkansas. The city recently required owners to hire two certified law enforcement officers on Friday and Saturday nights, holidays and special events. Officers provided security after midnight until the bar closed. The ordinance also stipulated clubs have adequate security staff (separate from the certified officers), as well as install proper exterior lighting, video surveillance and signage prohibiting loitering. 

To enforce the new rules, owners faced penalties for failing to comply with the mandate and for ongoing problems with violence in and around their club or bar. The chief of police had the authority to suspend or revoke the owner’s liquor license. 

Burgason's research found that there was still a significant risk of violent crime in the six months after the ordinance went into effect, likely the result of a greater police presence and focus on crime near the bars. However, within a year the researchers could detect no significant risk of violent crime within an eight-block radius of each club.

The analysis included seven of Little Rock’s private clubs and focused specifically on reports of robbery, rape, homicide and aggravated assault within that radius, during the hours of midnight and 5 a.m. on Saturday and Sunday mornings. The results were:

  • 2013 – 199 violent crimes reported (year prior to the ordinance)
  • 2014 – 154 violent crimes, a 22 percent decrease
  • 2015 – 119 violent crimes, a 23 percent reduction from previous year
  • From 2013 to 2015 violent crime dropped 40 percent

Burgason said displacement is always a concern within any ordinance designed to target crime in a specific location. Given the analysis included an eight-block radius around each club, researchers are confident crime was reduced and not simply pushed into a neighboring area.

There are several factors – hours, clientele, concentration of bars in one location – that can contribute to criminal activity in and around bars and nightclubs, Burgason said. Even though the causes may vary, the goal is the same, which is why Burgason said the Little Rock ordinance could work in other cities.

While this analysis only measured police presence, other measures required by the ordinance can be just as effective as a police presence. Burgason is working on another study that looks at lighting and video surveillance, as well as the use of street closures and barricades to reroute people in an area with a high concentration of bars and restaurants. Based on the initial results, Burgason says all these steps can have a significant effect on violent crime.

“Our response to crime is generally more reactive. If something goes wrong, you call the police after the damage is already done,” Burgason said. “However, if the establishment is set up with extra security or exterior lighting to stop or limit the tendency for violent behavior, it is a more proactive approach.”
