i am not blaming the mother for anything,what i am trying to say is that maybe if people were more aware of the warning signs of mental illness this could have been prevented,most of the mass shootings that have happened were done my mentally sick people that gave warning signs that something was going on with them,if friends and family see theses changes going on,withdrawing ,isolation,mood changes,anger they need to step in and seek help.we cant just assume anymore that people are just going thru something and step up and get them help
