Lansing, Michigan (WLNS) – A recent report on traffic stops in the capital from February 2021 to February 2022 breaks the general trend among more than 6,000 traffic stops made by the Lansing Police Department.

The report “Analysis of Lansing Police Department’s MATS data for 21 years” was written by Dr. David Carter and Ph.D. Joseph A. Schaefer.

Carter is a professor of criminal justice at the University of Michigan, and Schaefer is a professor of criminology and criminal justice at the University of St. Louis.

Of the 6,116 stops made by Lansing police, the most frequent were men.

Despite the tendency for black people to be dragged in more than expected from the census, experts say the trend is in line with data for 21 years and that there is no evidence of biased police practice. .



As a rule, men are dragged more often than women, and people aged 20 to 29 are dragged more often. The second most common age group that was discontinued were people aged 30-39 years.

Blacks were the most common minority group stopped, accounting for 38.7% of all traffic stops in the reporting year, despite accounting for only 23% of Lansing’s population.

Researchers say they focus on models, not population.

“It’s a nationwide practice,” said co-author David Carter. “What you’re looking for are patterns. Patterns in road stops and patterns in election searches ”.

Carter went on to say that using census data to try to identify police bias leaves too many variables to use as metrics.

“To take a city like Lansing, which has a lot of suburbs, with a state capital, with a university, a lot of people come and go,” Carter continued. “Thus, the demographic nature of the population and the ruling public there is different. Sometimes it can change every day. “

Carter also explains that police deployment plays another factor because many times police patrols see the highest number of calls. He says consideration is more important when officers decide to conduct a search.

“So we look at consent search, and we’ve been looking at them for years and see if there are any templates that stand out, that there’s more consent search in the template for colored people,” Carter said.

Carter says the review of the data has been going on for two decades, and during that time several notable cases of problems have been found in police practice.

How often are searches conducted? Whose cars are they looking for?

There are circumstances in which the police may search a vehicle without a search warrant:

  • Free and voluntary consent is given by the driver of the car
  • If the police intend to arrest someone
  • A terry surface search in which officers search for weapons to protect themselves and others
  • When the car is towed by police
  • If the officer sees illegal smuggling in the car
  • Parole is under search

During 82 traffic stops, items were found and / or confiscated. The predominant types of smuggling at bus stops were alcohol and drugs.

Weapons were found in 6.8% of searches.

Most searches were conducted on the basis of an incident for the purpose of detention, and the next most common type of search was consensus.

The main part of the stops with searches were black people, 167 searches were stopped out of 2364 people. The report shows that 3,009 white people were stopped and there were 105 searches.

According to last year’s data, more than 50% of black drivers who stopped were also searched, compared to 34% of whites.

Approximately 53% of these searches found smuggling in the first set of drivers, while a search for White drivers found something in 28% of cases.
