I know many won't agree, but I wonder sometimes if the lack of personal interaction in this country is somehow a part of the problem. People now text more than they have face to face communications. Young people are more into digital everything. They game a lot, text each other even when together and rely on social media to express themselves. There should be studies done about what were these shooters involved in, not so much content but method. When I grew up being a military brat I had to meet new people a lot and learn different cultures. Our childhood issues were settled face to face without parental involvement for the most part. It's harder to be violent with someone you have a real relationship with. Are there too many people having too much of there interaction digitally? I sure hope we can find a way to reach this type of person and pull them out of whatever issues they are having trouble resolving before it gets out of hand.
