what do you mean sharkbastard?
if a crime is reported i can guarantee someone gets in touch unless the crime is filed at source.
if someone rings up saying my car got broken into last night, then two things might happen.
the call handler will ask questions to determine whether there is any line of enquiry for an officer to follow up.
if there is no evidence, no cctv, no witness, its rained all night so no forensics - then its likely the crime will be filed at that stage because there is no realistic chance of solving it.
if there is cctv clearly showing an offenders face, or there is a witness, or forensic opportunity then the crime would be allocated to an officer for a call.
thats how it works. in my force - people are told on the phone whether its getting filed or allocated.
