This was a great find. I agree that, in Michigan, the courts seem to have increasingly excused police officers' violations of people's 4th Amendment rights. If one does a quick search of Michigan Appeals Court and Supreme Court opinions, one notices that oftentimes an officers' violation does NOT trigger an exclusion of the evidence... much as the article explains. It is also strange to me that officers are excused for not knowing the law, but we as mere citizens are expected to know it very well, lest we be charged with a felony for our ignorance.
