>> Traumatized students on their first day back at Marjory Stoneman Douglas High School, two weeks after a gunman opened fire in the halls and classrooms, killing 17 people. Many of the students carried flowers when they arrived, making their way through hundreds of police officers on site.>> It was really weird.
When I got into the classroom, it was kinda like everyone stared at each other and got a little silent, and then we all kinda reunited.>> I'm just happy to see everyone come together and support each other.>> You gotta take in everything with all the kids, the teachers trying to comfort you and all the students, and I really thank everyone for that.
>> We're never going to be back to normal, but it's just going to get us in the right direction again.>> The magnitude of the tragedy not lost on parents who accompanied their kids to school.>> So it's been very difficult and extremely sad for all of those victims and their families who don't get to come today and pick up their children.
>> But despite the horrific circumstances, most students showed up for class.>> On hand today were also approximately 150 counselors that were ready to listen, to provide support, and offer any help that was needed. They are also a lot of therapy dogs, there are over 40 of those on site today, and other animals in support, as requested by staff around the campus.
>> But not all the sprawling campus was reopened. The building in which staff and students were killed will remain closed as state lawmakers contemplate tearing it down and replacing it with a memorial to the victims. Meanwhile, a makeshift memorial has been growing outside the school with messages of remembrance and resilience.
