Just don't set up police and forget it. I've done so only for the enemy to invade and show the cops what real soldiers do. Nowadays I give the cops some guns.

This is true, but it depends on whether you prefer keeping the enemy from capturing the planet at all costs. If you would rather it be glassed than captured, then give your troops guns. If you'd rather the planet survive so that you can recapture it more or less intact, then you want to make sure your troops are unarmed, or they will repel the invaders and get obliterated from orbit for their trouble.

At least against the Ai. While I have heard of a few AI that will attempt to capture planets with troops, I've not heard that any are smart enough to alter their strategies to alter glassing the planet if the invasion is repelled.
