With the series of shooting all over the U.S, which we all know this is done to further divert attention from investigation going on. I think its should be legal for students/teachers to protect themselves. 
Gaddafi was taken down cos he is answerable to just himself. A country with no foreign debt and doesn't request for help from IMF. Nato had to turn everything upside down, I hope they like the new Libya now.

Police all over the world has long forgotten the purpose of it establishment. Rather than protect lives, they take it away.

Seems the world has gone mad. A politician empowering his constituent with shoe shining kit in my country, some people need brain formatting
