Which method is least effective in deterring criminals?

The method that is least effective in deterring criminals is allowing customers to enter through any doorway. This approach can create opportunities for criminal activity by providing multiple access points, which can make it easier for criminals to enter and exit the premises unnoticed.

In contrast, having good visibility to eliminate hiding spots significantly enhances security by ensuring that potential criminals have fewer places to conceal themselves, which can deter them from attempting any illicit activities. Installing video cameras serves as a visual deterrent, as the presence of surveillance can make criminals think twice about committing a crime due to the risk of being recorded and identified. Posting signs indicating limited cash on-hand can also deter criminals, as it communicates that the potential rewards of a theft may not be worth the risk if there is little to steal.

In essence, allowing access through any doorway undermines security measures, making it the least effective choice in deterring criminal behavior.
