Right. The point is that it would require a full police investigation, interviews, etc...
In my view at fault in these cases is the delivery company, they are in a hurry and don't bother doing a proper job. If they would be forced to eat the cost, this wouldn't happen anymore. Basically they are outsourcing their job to the police force.
Basically evidence.
If the police can't take evidence and solve a crime then fuck 'em.
