As the news coverage of the Virginia Tech tragedy continues, more facts are coming to light about what a troubled boy the shooter was. Which leads to so many questions that probably don't have satisfactory answers. I haven't watched full coverage-- I really can't bear to stay focused on what happened, but I have seen the photos of the shooter with his guns, and heard that much of what he wrote is disturbing and angry. I guess the most troubling aspect, is the fact that his behavior has concerned many people over a long period of time, and very few took any action to get help for Cho to protect himself and others. The people that did try to do something seemed to hit deadends in their assistance. I know it is easy in hindsight, to say something should have been done, but how do we stop people like this from falling through the cracks? How many times have I walked around or away from people that made me uncomfortable? Whose job is it to pay attention? Is it mine, or can I say it is someone else's fault? How do we learn from this?
