Marco Diaz-Munoz asks lawmakers to not act in self-interest' after two of his Michigan State University students killed

A college professor who taught two of the three students killed in the mass shooting at Michigan State University on Monday night - and came face-to-face with their murderer - is pleading with lawmakers to tighten controls on access to guns in the US.

In an interview with the Detroit Free Press newspaper published Friday, 64-year-old Marco Diaz-Munoz said no one should need more than one pistol to defend themselves and pleaded with legislators - who often are supported by pro-gun lobbyists - to not act in self-interest" as the country continues registering more than one mass shooting daily this year.
