From this position it is possible to swiftly [[speed strafing|speed-strafe]] right and exit the Lucerne Tower completely, free-falling through the level. You need to pick your direction very carefully, and uncrouch right away after you begin to move to get the speed needed to pull off the glitch properly.

A variety of positions lower in the level can be accessed extremely quickly by this method, including the secret "cheese room" (which is not actually ever used for speedruns), Cassandra de Vries' office, the room where the programmer deletes Dr. Carroll's file on [[Perfect Agent]], an external balcony which rings the office floors (a structure which was originally going to be an integral part of the level but was abandoned), the ground floor lobby, an area of pavement outside the Lucerne Tower's front door, and, most importantly, the basement elevator. You can also fall all the way out of the level into oblivion.

For speedruns, the Defection glitch can also be pulled off by landing on the head of a patrolling guard as he walks through the door that you usually use. This is tougher, but consistently faster.
