This is not a joke. I wish it would just be a joke.
It is a satire about the usual:
There was a shooting!
Restrict guns!
You cannot do that! Only guns prevent gun deaths!
Switch schools with guns and NRA with education lobby and you have the typical statements.
Attacks in educational institutions occur in other countries, but they are not mass in nature, unlike in the United States. For example, in September 2006 in Canada, a young man impressed by the massacre at the Columbine American school in 1999 (12 people were killed and dozens injured) came to Dawson College in Montreal armed with a self-loading carbine. As a result of shooting killed one and wounded 19 students. In January 2017, a teenager opened fire on his classmates at a private school in the Mexican city of Monterrey. Wounded a teacher and three children. In March 2009, in Winnenden, Germany, a teenager using his father's pistol staged a bloody massacre in his former school, and then on the streets of Winnenden and Wendlingen, during which 15 people were killed and 11 were injured. In March 1996, the British Dunblane man, accused of pedophilia, shot 16 children and one adult at a local elementary school. Another 16 people were injured. This was one of the bloodiest dramas in British history. In all these cases, the attackers committed suicide.
