We can put Breonna Taylor's death down largely to the failed war on drugs and the style of policing and extremely well armed drug gangs it has spawned. No knock, and 'ha ha, we sort of knocked and announced ourselves' home entries should not be permitted, apart from hostage situations and active shooters barricaded in houses. The DAs and police department love the war on drugs, because it has led to the legal seizure of money, as well as drugs and weapons. That can be a big source of revenue for the locals. Money has been seized, even when no drugs found, even when no charges brought in court. Conservative as well as liberal commentators and academics have written about what a disaster these seizure laws are -- really a great disgrace in what is supposed to be a constitutional republic/democracy, where the citizenry is assumed to have substantial inherent, constitutional, and statutory rights. Right to own property? Not if a DA or police department suggests that the money might possibly have come from the drug trade.
Barely announced police entries into residences with people inside are bound to result in tragedies like this. We also have self-defense and stand-your-ground (in many states) and right to own guns (different levels of licensing requirements in various states), so this sort of home entry is likely to result in an armed resident firing upon what he believes to be a home invasion.
Even if we can't kill the war on drugs, and we definitely should -- and transfer the $ to drug treatment and mental health programs -- 'he might flush the evidence' is a very poor excuse for these dangerous home entries.
If you are part of a police home entry team and are fired upon, it's natural and self-defense to fire back. You can't prevent this sort of incident by insisting that the police be slower to shoot. It is the sudden home entry itself, which is the problem.
Drugs remain very easily available in America, as they always have been. The war on drugs has accomplished nothing, other than death, pain, and increasingly well armed police and criminals.
Our governor wants to legalize recreational marijuana. If the feds don't interfere, it would be a step forward, even if done for the wrong reasons (to raise revenue rather than to deal with marijuana in the best possible manner).
Actually, the end result would be good. The biggest danger from marijuana comes from the feds periodically spraying marijuana fields with herbicide.
