It seems that more schools are making the change to allow for legal carry on campus. It may not prevent someone from attempting to shoot up a school, but hopefully it would bring a quicker end with less loss of life if they did. Seen at misguidedchildren.com:
Ever since the very first school shooting in modern times, there has always been a demand for educators to be able to carry a means to defend themselves, which has become something of a concern for Oregon School teachers, among others. In fact, that is exactly what a school district in Oregon has done. Teachers have the proper credentials to carry a weapon will be allowed to do so. Marshall Porter, who is the chairman of the St. Helens School Board, has stated that the measure would give teachers the same right as ordinary citizens.
Porter went further making the following statement: “The current law in Oregon allows for anybody to conceal carry on school grounds, to exclude our staff seems like they’re being punished. They should have a right to protect themselves if they so choose.” There are a total of seven schools that fall under Porter’s jurisdiction.
