>>3928767Can't tell if you're serious or not, but essentially the entrance was a bottleneck. More people were trying to leave through it than was physically possible in that small space. So, it got clogged up, and the rate at which people could leave was slower than was necessary for the rate at which the fire was spreading. Also, if you watch the video here
>>3928649 you'll see at 1:50 that people actually fell over and were being crushed. In a situation like that, you've got a wall of fallen people blocking the entrance with people behind them trying to get past. The ones closest to the people wall see this and no doubt want to back up, but the people further back don't know about the blockade and are pushing forward, making the situation worse.
Here are some other videos about crowd crushes.
