Yep. For one reason, they are extremely subjective. If a cop wants you to fail, you will fail, no matter what you do.
But I don’t believe a breathalyzer can catch drugs in a person’s system.
I sure wish there was an easy answer here. False arrests are terrible things. But so is letting a drug-impaired person go, to maybe kill someone further on down the road.
There is an easy answer. Blood tests will catch most things. Most pleases they need a warrant for that, but they usually have a judge sitting around by the phone. And of course you can waive that. Field sobriety tests can be refused without punishment pretty much everywhere, and if you can you should, no matter what. And they ain’t actually stopping anybody because everybody in the drug culture already knows that and says no.
It is not the best solution but the police arresting people who are completely innocent for financial gain is unacceptable.
