Final answer:
The trend to call for broad discretion for police officers among policing experts is true; discretion is key to law enforcement effectiveness. Other related statements about historical government and legal facts varied between true and false based on their historical accuracy.
Step-by-step explanation:
Regarding the trend among policing experts to advocate for broad discretion for police officers, the statement is true. Discretion allows officers to make judgements based on the circumstances they encounter and is a critical aspect of effective law enforcement. For example, in daily interactions with citizens, such as a traffic stop, officers use discretion to decide whether a warning or a ticket is appropriate based on the situation.
Addressing the other exercises, Dillon's Rule actually restricts local government autonomy, making the statement false. The necessary and proper clause has expanded, not limited, the power of the national government, so that statement is also false. Pennsylvania's constitution during the Revolutionary Era was indeed one of the most conservative, making this statement true. And the temperance movement was indeed influenced by increasing urbanization and immigration, thus the statement is true.
Colonial governors did have the right to veto legislation, so that statement is true. The Antifederalists and Federalists had opposite views, making the statement about their identities false. The colonists' objection to taxation involved representation rather than the application of tax revenues, therefore the statement is true. Finally, John Locke viewed the Glorious Revolution as legitimate, confirming that this statement is also true.
