Another child shot to death

How many children's deaths must we tolerate before something is done?  If no one wants to blame the child who pulled the trigger, then there's another someone to blame, the so called 'adult' father who not only owned the gun but showed it to the 11 years old shooter.  People should not only be lawfully checked for mental illness before being allow to make such purchases but also be tested for 'parental stupidity'..............................marge
