He knew that overly suspicious ( and therefore aggressive) police officers could create distrust between the police and the public. That’s why the four officers in Sherman’s experiment went through specialized training and only worked in District 144 at night—Sherman wanted to make sure that they knew how to target the right kind of traffic stops, in the right kind of locations, at the right times, that led to the right kind of searches.
How to catch a criminal?
Police officers are taught that savvy criminals would be careful not to make any obvious infractions. So they learn how to use creative tactics to catch criminals in the act. Here are some examples: 1 Look for air fresheners in the car—they could indicate that the driver is trying to hide the smell of drugs. 2 Park your squad car in a suspicious location and wait for drivers to make an illegal stop when they see the car. 3 Look for fast food in the car—this could indicate that the driver is unwilling to leave the car for long periods of time because of expensive cargo, like drugs. 4 When going through a routine traffic stop, draw out the interaction for as long as possible. Ask a lot of questions and watch to see if the driver slips up and gives inconsistent answers.

Overview
The Kansas City preventive patrol experiment was a landmark experiment carried out between 1972 and 1973 by the Kansas City Police Department of Kansas City, Missouri. It was evaluated by the Police Foundation. It was designed to test the assumption that the presence (or potential presence) of police officers in marked cars reduced the likelihood of a crime being committed. It was the first study to demonstrate that research into the effectiveness of different policing style…
Design
The experiment was designed to answer the following questions:
1. Would citizens notice changes in the level of police patrol and crime?
2. Would different levels of visible police patrol affect recorded crime or the outcome of victim surveys?
3. Would citizen fear of crime and attendant behavior change as a result of differing patrol levels?
Major findings
1. Citizens did not notice the difference when the frequency of patrols was changed.
2. Increasing or decreasing the level of patrol had no significant effect on resident and commercial burglaries, auto thefts, larcenies involving auto accessories, robberies, or vandalism–crimes.
3. The rate at which crimes were reported did not differ significantly across the experimental beats.
Conclusions drawn
The Kansas City Police Department drew the conclusion that routine preventive patrol in marked police cars has little value in preventing crime or making citizens feel safe and that resources normally allocated to these activities could safely be allocated elsewhere.
A significant factor realised was that crime prevention was more highly dependent on the willingness of citizens to report suspicious and/or criminal behaviour to police than the levels or …

History
As a conservative Republican Senator from Kansas, Brownback had been reelected by large margins in 1998 and 2004, and had also run briefly for president in 2008, withdrawing before the primaries began. In 2010 he ran for governor, defeating his Democratic opponent Tom Holland 63.3% to 32.2%.

Impact
Despite its record, and the fact that "many experts regard the Kansas tax cuts as a failure", the 2017 Republican tax cuts ("Tax Cuts and Jobs Act of 2017") has some of the same elements of Brownback's policy, and "many Republicans still embrace the ideology" behind the Kansas tax cuts, according to National Public Radio.
Several sources have compared the Kansas experiment to the 2017 federal tax cuts, which wer…
Explanations and defense
According to critical observers, part of the reason for the large revenue loss was that the new 0% tax rate on pass-through business income was "exploited" and had "become a loophole" for taxpayers. Instead of 200,000 small businesses taking advantage of it, about 330,000 entities used the rule; among them were large limited liability law firms and oil exploration companies. These companies included a large number of subsidiaries of the Wichita-based Koch Industries, …
