Well if you actually think about what you're saying, you'll realise why it's such a stupid suggestion. You put cameras in every home, you have to look thru all the cameras in every home for a change of finding something wrong, which means you're looking into the homes of mostly innocent people. Even the good cop would have to be. However, if you place the camera/tracking device on the thing that's actually being stolen, and activate it when it is reported stolen (many cars have this) then any interaction you have with that security device is not invading anybody's privacy, except for whomever's trying to steal it, and they don't get privacy protection. An abused system doesn't mean a useless system, it just means measures should be put into place to stop abuse, for example, the owner of the thing in question (laptop, car, or in this case it should be the kids' parents) has a security code that enables tracking software, so the tracking software cannot be used without their authorisation. Problem solved. Without any need to throw out the baby with the bathwater. That wasn't so hard, was it?
