Use the Irac method law to answer the question below.

The manager of Trinity Parks wanted police protection due to possible terrorist threats, which over the past few months have targeted several play parks. The Police suggested that a mobile patrol would be enough based on intelligence, but the manager insisted on a permanent police presence. The manager then offered to pay, if the Police will provide a permanent protection over the next two weeks.

The police agreed thereafter to provide 10 officers at a rate of $100 per day, per officer which they maintained over the two week period.

At the end of the two week period, the Police Authority sent an invoice to Trinity Parks for their services, but the said Manager refused to pay and argued that the Police are under a duty to protect the company from any pending lawlessness, and as such they cannot charge for their services.

Please advise the Police Authority on this matter
