Should the police be required to investigate every incident of shoplifting, regardless of the stolen value?

The UK is experiencing an 'epidemic' of high street retail crime, with shoplifting incidents reaching record highs. Due to budget cuts and resource prioritization, police forces frequently screen out or fail to attend reports of shoplifting if the stolen goods are under a certain value (often £200). Retailers complain that this de facto decriminalization has emboldened organized gangs and aggressive thieves who calculate they will face no consequences. Proponents of mandatory investigation argue that broken-windows policing is essential to maintain order, protect shop workers from violence, and prevent high streets from collapsing. Opponents argue that forcing underfunded police to chase minor thefts would dangerously divert crucial resources away from investigating major crimes, or unfairly penalize the desperately poor.
