There is a huge difference between fostering a single child (especially one's own grandson!) and working as a prison guard. I would never volunteer to "foster" an inmate, or an entire cell block of them, in my own home.
There has to be a provision for reviewing circumstances of each case. There is a lot of room to wiggle in between having one's gun collection lying around on various tables in the house, and having a P32 in the pocket and anything else locked up in a safe.
fpg72, I take it your son was "adopted from the system" prior to his seventh birthday?
No, I will never foster a child. While I believe that my wife, daughter, and I could provide a safe and productive home, I would not be able to reconcile a state requirement that I give up my right to provide yet another protective measure for my household and all of its members. On top of that, my wife is Russian, and it's just not in their culture (other than with family, in which cases they are even more inclined than we Americans seem to be at times.) She is a grade-school teacher, and the stories she has would make you want to foster them all...
