i dont have kids my self but i have 3 younger brothers that i have had to take care of granted they are now a little older the youngest at 12 but being the older brother i help teach the youngest about what could happen and some tricks to do to where they are unaware of what is going on but it is a good thing to teach them what to do if something like that were to happen and if your kid is interested in gettting into some kung fu classes or anything mma something i say let them do it.
as an officer i know what its like to have people aroound me that have raped children and have abductied kids and it doesnt sit right with me especially when i am the one that has to take off the cuffs to let them out of the jail and let them go free that is the hardest thing about my job is to have to by law let that kind of person out of jail. but like you have said we have to keep it G rated but i know how you feel on this one even though i dont have kids of my own
