...I taught my boys at 3,4,5 the difference in feel/weight between their toy guns and my real ones...what to do if they ever encountered a real gun out somewhere or at a friend's house....what guns were for and not for....by the time they were 8, they were shooting...by 10---good enough and trained enough to repel boarders....no mystery or hiding...guns are tools...and a hammer with a "safety lock" is no good at all....guns are for stopping unexpected trouble in a matter of seconds...no good locked up, no good locked, no good unloaded....the state of instant readiness is part of the picture.....many places in a home where a gun can be ready and undetectable by guests(i.e. other children)---we just don't need locks on guns....what we DO need is enforcement of the existing laws to punish effectively those who abuse them...but that'd require blaming one's actions on oneself...and the crowd today needs to avoid that at all costs....blame the corporation...blame the gun...but a PERSON standing up and saying "I was wrong".....not PC....
