Fig- I'm with you on the discipline thing. And I understand your take on the vehicular manslaughter scenario.
The difference being, and don't confuse them, is it is legal for your kid to drive (I hope). The state has decided your child meets the minimum requirements for licensing, and so he has the RESPONSIBILITY to do so legally. Also, you supervise your children and/or block their internet access. I think if the people who claim ignorance had done what you've done, they wouldn't be where they are. Is it the parents RESPONSIBILITY? Yes, it is.
If a parent (in CA, so forgive me) leaves his/her weapon loaded and the child gains access and shoots themselves or someone else, guess who's also getting prosecuted? The parent, and rightfully so. Now if the weapon is not openly accessible, and not loaded, and the child loads and shoots himself or others, well, that could be argued as theft, and the parent would not be legally RESPONSIBLE. (But would still be negligent in my opinion)
Yep, what I'm saying is if you have children, you should be RESPONSIBLE for their actions (as the law, including civil law, states here in CA). And trust me, if they screw up, it's a reflection of you as a parent 9 times out of 10. If you don't want to be RESPONSIBLE for your children, don't have them.
Where does RESPONSIBILITY lye.
Judge for yourself.
