Sure, but in order to find drugs in your housing THEY NEED A WARRANT.<quoted text>
You are clueless. In many major cities you can and will be removed from public housing if you even allow someone to possess drugs in your domicile.
Punishing someone for committing an illegal act is legitimate. Depriving someone of their constitutional rights is not.
It's perfectly legal for an officer to stop every car that passes a given point, informing the driver that they're watching for drunk drivers, and asking the driver to pass along that information to friends.<quoted text>
There is nothing illegal about requiring a drug test to receive government funding. A DUI checkpoint is a search without probable cause.
And if the driver has alcohol on his breath, the officer has probable cause for conducting a field sobriety test. Or if the driver consents, the officer can conduct a field sobriety test.
If the officers stop EVERY driver passing a point and give them ALL field sobriety tests, that's illegal, and courts regularly throw out all those tickets.
Except that MOST private sector workers are NOT drug-tested.<quoted text>
On the other hand, I agree that all city, state, and federal workers should be drug tested just like the private sector.
The "no search without probable cause" rule amounts to "if it ain't broke, don't fix it." That's a pretty good rule to follow.
