Final answer:
The smoking ban in Newtown without a public vote, reflecting prevailing social norms, is likely based on a social conservatism perspective, valuing public health and common good.
Step-by-step explanation:
Newtown's law criminalizing smoking in public places such as parks without a public vote and based on prevailing social norms can most likely be attributed to a social conservatism perspective. This school of political thought emphasizes upholding traditional moral standards based on natural law or long-standing traditions of a region. By enacting this decision according to what is deemed socially acceptable, Newtown is prioritizing the common good and public health over individual freedoms to smoke in public spaces.
