Crash!

Heard a loud crashing sound near my office, went out to take a look and saw this. Just in case the photo ain't clear, it's a door with just the frame but the glass is completely shattered. Either :

1. a STRONG person swung the door too hard
2. a BLUR fella walk through the glass
3. a VERY FAT person (think "Norbit-Size") thinks he/she can squeeze in between a gap while the door is closing.
