There is a false trade-off between privacy and law enforcement. It's a false dichotomy, and a false excuse. The government has no cause to violate the privacy of its citizens in their persons, houses, papers, and effects like that. When people do drugs, their activities are almost always not only apparent to neighbors and others, but highly disruptive to the functioning of a peaceful society -- and there is no lack of genuine probable cause to execute a warrant in those cases. The same with child pornography and other bugaboos of anti-privacy advocates. People aren't surfing that kind of smut anywhere in real life without the neighbor's children being aware of something very unseemly going on if they are not victimized themselves. How can the U.S. government be so aggressive at spying on its own citizens, and yet at the same time so enabling of drug abuse, sex trafficking, and other openly criminal activity, which it takes no action whatsoever to stop? Why is the U.S. government so extremely aggressive in prosecuting as a crime the mere possession of firearms or ammunition, which is almost always deemed "unlawful" on some technicality or another, in total ignorance and defiance of the Second Amendment of the U.S. Constitution?
