"Pretextual Traffic Stop" is one way adopted to achieve this. Police officers do this by stopping motorists under the premise of enforcing traffic laws, but in reality, they are conducting speculative criminal investigations.
This generally occurs without the drivers' consent and may facilitate violent conflicts.
Anger, frustration, or wrath are possible reactions for someone headed somewhere, especially when there's no reasonable cause to stop them. Each side striving to outdo the other may result in violence. In this case, a trigger-happy police officer may likely shoot helpless, unarmed citizens. Consequently, public confidence in the police force falls and the statement, "Police is your friend" loses its sensory charm.
Police in a specific developing nation, Nigeria, deploy ‘pretextual traffic stops’ as a technique of obtaining money from motorists. There have been cases in which police have fired shots at a driver who has refused to stop. There is still a pending case of such that involved six spare parts sellers, between ages 21 and 25, who were alleged to be armed robbers. They were killed in 2005 by some officers who claimed that they acted on superior orders.
I'm open to correction, but I'll maintain my position that it's legal robbery as individuals in positions of authority are pretending that they are not aware and have not ruled against the inhumane crime. It is also a dishonest style of functioning.
This activity is also referred to as ‘police roadblock’, ‘police trap’, ‘vehicle checkpoint’, etc., according to Power Thesaurus. I assume that the original motive behind its enactment was to reduce crime. I advise that they leave it that way. The police officer with that detail may seek an official permit and visit the suspects in their dwellings if they have any criminal investigations to conduct on any residents. This, in my opinion, will prevent the violation of the rights of clean motorists and foster roadside peace.
