Oh come on, the police I know are more right wing than I am (and that ain’t easy to achieve). Course I only know police in SW Missouri, could be different in St Louis or KC.
Yep, I can’t imagine policemen in certain areas of the state taking this seriously at all. Parts of Missouri are very conservative.
You people are deluding yourselves. These same conservative cops that you know are more than happy to trample on your Constitutional rights at any time, see below. They'll all fall into line because priority #1 is keeping their jobs.
The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.
Missouri police departments commonly employ sobriety checkpoints at set locations, where all drivers passing through are stopped and questioned regarding their alleged intoxication, without any observed traffic violations being committed, or prior probable cause to arrest for DUI / DWI.
