Is it wrong to monitor your childs text messages?

I'd absolutely support this. As far as I'm concerned, most 15 year olds shouldn't even NEED a Cell-phone. Regardless, and if they should, the parent should get this. This isn't an "invasion of privacy", this is Good-parenting which most American's don't even do. The next thing you want is your 15 year old sending a nude to some kid then getting into a court case about how your kid distributed child pornography. Also, if a parent is PAYING for the Cell-phone, THEY can so whatever they want and the kid should abide by that.
