When a shooter opened fire on YouTube's campus before killing herself, Silicon Valley didn't just experience a tragedy that's rocked other communities and prompted an intense debate over gun control in the United States. The incident may also have prompted a rethink among tech companies which have enjoyed a culture that's embraced open spaces, including cafes, restaurants and gift shops, shared with the public.

While there have been a few incidents involving gun violence at a tech company, they are rare. Two years ago, an Apple engineer reportedly committed suicide by shooting himself in a conference room at the company's Cupertino, California, headquarters. In 1988, a fired engineer at ESL Incorporated, a software design and hardware company, killed seven people and injured four at its offices in nearby Sunnyvale.
