NOW AN INVESTIGATION REVEALS THE
ISSUE IS MORE WIDESPREAD THAN
YOU MAY THINK.
AARON GILCHRIST HAS MORE.
>> Reporter: TIME AND AGAIN THIS
COUNTRY HAS BEEN ROCKED BY GUN
VIE LEN.
2007 IN VIRGINIA TECH, 32 PEOPLE
SHOT TO DEATH.
>> I'M SHOCKED HOW ANYBODY COULD
DO THIS TO ANYBODY ELSE.
>> Reporter: 2013 IN SANTA
MONICA COLLEGE, THREE PEOPLE GUNNED DOWN.
GUNNED DOWN.
to Shirlee or Thomas
>> WE HAVE AN ACTIVE SHATNER
LIBRARY WITH AUTOMATIC WEAPONS.

THIS YEAR AT MICHIGAN STATE.
THREE STUDENTS MURDERED ON
CAMPUS.
PROFESSOR MARCO DIAZ MUNOZ SPOKE TO JESSE KIRSCH ABOUT
SPOKE TO JESSE KIRSCH ABOUT
TRYING TO PROTECT THE STUDENTS
IN HIS CLASSROOM.
>> THE ONLY THING I COULD THINK
OF WAS TO SQUAT AND PUT MY FOOT
AGAINST THE WALL TO PULL THE
DOOR.
>> Reporter: DIAZ MUNOZ WAS ONE
OF MSU'S 1,300 CLASSROOMS AND
HAD NO WAY TO LOCK THE SHOOTER
OUT.
IT'S AN ISSUE NATIONWIDE.
NBC NEWS FOUND SIX OTHER COLLEGE
SHOOTINGS SINCE VIRGINIA TECH
WHERE SOME CLASSROOMS HAD DOORS
THAT DID NOT LOCK INCLUDING
MICHIGAN STATE, THE UNIVERSITY
OF ARIZONA, UNC-CHARLOTTE, SANTA
MONICA COLLEGE, THE OHIO STATE
UNIVERSITY, AND UCL, A.
EACH SCHOOL
CONFIRMING TO NBC NEWS THE
STUDENT COULD NOT LOCK EVERY
DOOR FROM THE INSIDE DURING THE SHOOTINGS.
SHOOTINGS.
to Shirlee or Thomas
>> IF I COULD HAVE LOCKED THE
DOOR RIGHT AWAY, IT WOULD HAVE
BROUGHT COMFORT.
>> Reporter: I SPOKE TO A GRAD
STUDENT AT UCLA WHO WAS THERE
WHEN SHOTS RANG OUT IN 2016.
HE TWEETED THIS PHOTO OF THE
LOCKING SYSTEM HE COBBLED
TOGETHER SINCE HE COULDN'T LOCK THE COMPUTER LAB HE WAS INSIDE.
THE COMPUTER LAB HE WAS INSIDE.
to Shirlee or Thomas
>> THE FIRST THING I DID, I
LOOKED FOR ANYTHING I COULD USE
TO SECURE THE DOOR.
THE NEAREST THING I COULD FIND
WERE SOME CABLES AND CORDS.
ANYTHING TO SLOW ANYBODY DOWN
THAT WAS TRYING TO GET IN.
>> Reporter: AT UCLA AND ALL THE
OTHER SCHOOLS EXAMINED AFTER
THEIR CAMPUS SHOOTINGS, LOCKING
SYSTEMS WERE EITHER REPLACED,
INSTALLED, OR ARE BEING
INSTALLED IN CLASSROOM DOORS.
>> IF WE HAVE NO ABILITY TO
CONTROL ACCESS AT ALL, WE HAVE NO SECURITY.
NO SECURITY.

>> Reporter: PAUL TIMS IS A
SECURITY EXPERT WHO SAYS
COLLEGES HAVE TO PUT THE DAYS OF
OPEN BUILDINGS AND ROOMS BEHIND THEM.
THEM.
to Shirlee or Thomas
>> I DON'T KNOW OF ANY
UNIVERSITY FACILITY BEING
DESIGNED TODAY.
WHAT WHERE SHE MOSTLY IS THE
RETROFITTING OF THE FACILITIES
THAT DIDN'T HAVE THEM TO BEGIN
WITH.
>> Reporter: JUST WEEKS AFTER
THE SHOOTING AT MICHIGAN STATE,
THE UNIVERSITY DECIDED IT WOULD
INSTALL THE LOCKING SYSTEMS ON
THE CLASSROOM DOORS ACROSS THE
CAMPUS.
AND THEY TELL NBC NEWS THEY ARE
STARTING THAT INSTALLATION ON
MAY 8.
TIM SAYS COST MAY BE A REASON
THAT PUTTING NEW LOCKS ON THE
OLD BUILDING HAS BEEN MORE
REACTIVE THAN PROACTIVE.
>> WE'RE TALKING ABOUT HUNDREDS
OF DOLLARS AT LEAST, THE
INSTALLATION, ALL OF THOSE
THINGS.
IT'S NOT FOR A CLASSROOM DOOR,
AN EXPENSIVE VENTURE, BUT THAT'S
WHAT WILL MAKE IT SOMETHING THAT
CAN BE CONSIDERED.
>> Reporter: SCHOOLS ACROSS THE
COUNTRY ARE NOW INSTALLING LOCKS
AS A FIRST LINE OF DEFENSE
AGAINST THE POSSIBLE ATTACKER.
>> AND AARON GILCHRIST IS
JOINING US NOW.
YOU KNOW, TO UNDERSCORE, WE ARE
TALKING ABOUT LOCKING FROM THE
INSIDE, RIGHT?
>> RIGHT.
>> AND SO A LOT OF CAMPUSES HAVE
THEM ALL OVER THE BUILDING.
ARE WE TALKING ABOUT
RETROFITTING ALL OF THOSE AND
WHERE ARE WE IN TERMS OF NEW
BUILDINGS?
>> THE NEW BUILDING AS YOU HEARD
THEM SAY THERE, THEY'RE BEING
DESIGNED WITH THE DOORS THAT
WILL LOCK FROM BOTH SIDES AND AT
LEAST FROM THE INSIDE AND SO
TEACHERS COULD LOCK DOORS WHEN
THEY NEED TO BE AND IN MANY
CASES WE FOUND THEM BEING
RETROFITTED AND PUT IN PLACE AND
LAWS THAT ARE BEING PASSED, TO
MAKE SURE THOSE OLD LOCKS ARE
REPLACED.
THERE ARE OTHER REGULATIONS TO
CONSIDER.
AND THE REASON WHY THEY'RE THERE
IN THE FIRST PLACE, THAT YOU
HAVE TO BE ABLE TO GET OUT.
THAT'S STILL THE CASE, BUT THEY
HAVE EVOLVED, SO THEY COULD
