If you're paying attention you will notice two things: these cases are almost entirely drug cases, and that drug prohibition is failing to make drugs scarce.
So your premise is that all drug laws should be abolished/not enforced. Sorry but I only partially agree. Certain drug laws, marijuana for example, are overreaching. Other drugs do cause harm to society.
nothing confined to consenting adults should ever be a crime.
I agree but some drug consequences are not confined to consenting adults. Some drugs cause people to be unable to hold jobs, cause them to commit crimes to support their habit, etc. I realize that alcohol does similar things but to a much lesser extent. The percentage of productive crackheads is much less than the percentage of productive alcohol use. The consequences of this drug use is spread to the rest of society in welfare costs, health costs, insurance costs, policing costs, etc.
favored following the Constitution over prosecuting a drug criminal.
The problem with the US Constitution is that it is imprecise.
The right of the people to be secure in their persons, houses, papers, and effects,[a] against unreasonable searches and seizures, shall not be violated
The issue is around the word "unreasonable" which can be interpreted differently by different people. What is unreasonable to one person may be reasonable to another. Too many people seem to interpret this an "any search without a warrant" but that is not what the Constitution says.
