Did anyone read the latest news today? The problem wasn't the ease and availability of guns. He could have purchased weapons in any state, any time in the past. He had a clean record. It's a weak argument.
The problem was that he was picked on as a child, in grade school, middle school, and high school. He was ridiculed and made fun of. He was told to "go back to China." His parents brought him here from Korea for a better life, while both worked at a laundry mat. Imagine how hard it would be for us to move to Korea, learn a different language, and be made fun of every day of our lives with no alternative.
Teasing and bullying in no way make it right to open fire and kill others, but one can see the effects teasing and bullying play on children later in life. I'm sure everyone here was teased or bullied in the past. This kid must have been the laughing stock of the school. His boiling point exploded after dozens of years of pent up anger. It seems no one cared enough to open up to him at a young age. It could have been the busy DC school system, or his busy parents. Either way, he was left to fuel his own fire until it was too late.
