He thought it was a drill because for a year and a half the students were told that there was going to be a school shooter "drill" that was set to be as real as possible, shooting blanks, with a SWAT team and helicopters.

Watch the video here, and skip forward to the end at 1:06:00 where Holgate exposes the drill:

In an explosive interview with Parkland shooting survivor Thomas Holgate, a number of inconsistencies set forth by the MSM, and circumstances surrounding the shooting and the school itself were discussed, shedding further light on yet another confusing story that seems to take another twist with each passing day. Earlier today, we reported that emergency responders were told to wait outside while the children were bleeding out in the school. Soon after, Fox News' Laura Ingraham revealed sources told her the Sheriff's Dept instructed the Broward Deputies NOT to enter the school unless their body cameras were on.

During the interview, Holgate noted that the shooter was only in the school for approximately nine minutes, and during that time period he killed 17 people, in the chaos, and due to outdated security cameras with 20-minute delays, people were shuffling in and out of locations unaware of the shooter's location.
