So far tour buses are still winning over lunatics on shooting sprees as far as causing mass death and carnage by a long shot. I think like a dozen people, including children, died in just one tour bus accident. This was on the news for just one day compared to the Seattle school shooting or the Nevada shooting will be.
Perhaps we should look into banning tour buses before we ban guns as many more lives would be saved.
P.S.
Some psycho decided to ram their car into a crowd full of people in Bellingham last week on the very street that I walk through at night on weekends on the occasion. One person was killed, and two critically injured. It was an intentional vehicular homicide. This did not even make national news, but only hit the local Seattle news sources. Had a gun been used, it would have been national and international news.
