alt Hacker NewsWe are talking about reasonable searching then. Police do go searching 24/7. They are called patrol units and they are active looking in public for crime. Just because there is technology doing the patrol and remember what is seen that doesn't change anything. Technology is making law enforcement more efficient. Instead of having to scale enforcement by hiring more humans, we can now purchase technology instead.
Law is more complicated than that. Constitutional rights trump everything else. You have a right to be protected from unreasonable search, more than the police have the right to track your movements at all times for no particular reason. If what they do violates your constitutional right, it's illegal.
