If policemen had as much power to enforce the law as Congress had under the Articles of Confederation to enforce taxes and raise troops, what sort of tool would most accurately represent their enforcement powers?

under the Articles of Confederation, Congress could regulate the army, but could not compel the states to send troops. In other words, it could not really raise troops.

As for taxation, under said articles, Congress had no power whatsoevar to tax the states. It could only earn revenue by asking the states for money.

If policemen had as much power as Congress under the Articles of Confederation, then, the police would practically be powerless. I would have to look for funding through private donations, because it would not be entitled to any tax money.

Police would also probably be understaffed, so it would have to rely on voluntaries and people who have a passion for law enforcement.
