BTW, there usually AREN’T any LEOs around when problems occur.
And if there was one around all the time to prevent problems, would you be okay with that?
A LEO standing in front of your house at all times? Making sure you didn't break any laws? Maybe they could come into your house and check your light bulbs and the setting of your thermostat?
Or, maybe it'd just be better to put a black box in your car, a red light camera at every intersection, and speed cameras along every mile of interstate. Is that what you're advocating?
LEOs are there to RESPOND to dangerous situations. They're not meant to hover over a free people, watching their every movement. They're also not magical fairies hovering above every human interaction, ready to intercede when something goes wrong.
For Christ's sakes, grow up.
