The glass door of the gym could be shattered with a single gunshot. Fortunately, the cabinet material was good, and it was large enough to completely block the entrance.
People inside also pushed some fitness equipment against the entrance cabinet.
Once they were sure it couldn't be pushed open from outside by human force, they all retreated to the opposite corner, with no one near the entrance.
Although it couldn't be pushed open, there was a risk of bullets coming through, making the entrance very dangerous.
While they were inside blocking the door, reinforcements arrived on the sixth floor.
Kevin Clark and Charlotte Lane fought with them for a while outside, buying time for those inside to block the door.
When the situation inside was more or less under control, the two went to the safety passage.
