Most people would be appalled if they saw what the police get away with when they ask for search warrants. In the two areas I have personal experience with, the process of getting a warrant is an administrative inconvenience to the police, not the fair review that it's supposed to be. It's also important to keep in mind that it's similar to a prosecutor getting an indictment -- it's the law enforcement side telling only their side of the story, twisting facts however they please with no rebuttal, being told to a judge that maintains regular working relationships with these people and whose main concern is making sure the affidavit covers their ass enough not to get overturned on an appeal.
