Reading this thread I see why we have seat belt laws, helmet laws. People want to bring the full cohersive power of the State to bear, guns, money, personell, jail, to compell everyone to be “reasonable”. Freedom has risks. Risk has consequence. Therefore Freedom means accepting bad outcomes. If you don’t want bad outcomes, eliminate risk, at gun point ultimately.
If you don’t wear your seat belt, your neighbors have decided that you should. Ultimately cops will shoot you to make sure you pay your fine if you object to the enforcement of that law too strenuously.
Just so you know, I may think these parents lacked sense, , I may think this whole thing was a tragedy in the making, never should have taken place, but I would not want the government or anyone else to stop them. Just as I believe they should have the freedom to sail off the end of the earth if they want to, I have the freedom to call them morons if I want to!
