Nobody said their job was "easy" in the hiring advertisement! When you get a Judge to agree that their is adequate reason and gain a warrant, you use your resources to surveil the target in public/private, using your considerable means as a law enforcement agency. Drones, bugs, malware, other espionage techniques. This is nothing more or less than these agencies complaining that free peoples are making their jobs harder. One big problem is cowardice: it is easier and safer to attack the liberties of law abiding citizens (because they won't shoot you in the face), in the hopes that, by sacrificing your citizen's liberties you might pick up a few more incompetent bad guys. Its way more dangerous to actually go out, do your job, and surveil a dangerous bad guy, who will shoot you in the face. If that's a problem -- then the law enforcement complainers need to go get a new, safer job, and leave the heavy lifting to their braver counterparts.
