Securing a conviction for murder requires a scrupulous chain of custody for forensic evidence and that sometimes means an extended process to recover said evidence from the crime scene in a suitable manner. I'm sure you'd be over the moon if a member of your family was murdered and the trial of the alleged perpetrator collapsed because the police did a botched job of searching the scene and recovering evidence.
If your car was parked in a car park and someone was killed less than 100 yards away you certainly would be allowed to just jump in your car and drive away until the police had given up the scene.
If there's even a suspicion of these crimes, normal practice worldiwde would be for a large number of police to be involved, and generally quickly (though for remote locations, slower).
You don't appear to understand my point about efficiency. A line search is doubtless tedious and needs to be carefully organised and carried out centimetre by centimetre, but many hands, while perhaps not making 'light work', ought reduce the time it takes. Why is the line still closed after 24 hours?
