It was a horrible thing that happened in Tuscon Arizona. There were 5 people killed and more people wounded. Among the people that were killed was a federal judge and a 9 year old girl. The moment of silence was observed all over the country.
The moment of silence was a rare change in the schedule of the Supreme Court. Chief Justice John Roberts as well as his 8 co-workers paused after hearing their first oral argument. They briefly spoke about how the shooting that happened was senseless. The moment of silence was held primarily because of the fact that Federal Judge John Roll was killed and Congresswoman Gabrielle Giffords was horribly injured.
The shooting that happened targeted Congresswoman Gabrielle Giffords. The 22 year old shooter Jared Laughner was able to get up to her and shoot her pointblank. Where was her security? We are glad that the country took a moment of silence for these victims.
