Crazy Brit- you are being a little extreme. To complete your thought: Physically locking it won’t work because there are safecrackers. And even if you put it in an uncrackable safe, the neighbors’ safes are crackable. Finally, stores sell unlocked tablets for $100. If your kid can’t figure out how to steal $100, he’s an idiot.
Bottom line: some safeguards are often necessary. Panic and extremes are pointless and often arouse rebellious feelings in children.
