What has Cadet Merrill been up to?

Well, I am so glad that you asked, since I just got a copy of him getting sprayed with OC. What is OC? Well, OC, or Pepper Spray, is an inflammatory agent; not an irritant. When someone is sprayed with OC pepper spray, the person's eyes slam shut. Even if someone does manage to get their eyes open, they won't be able to see because OC dilates the capillaries and causes temporary blindness. Additionally, instant inflammation of the breathing tissues restricts all but life suport breathing. They double over coughing uncontrollably. No, I didn't write that, they did. There is a better explanation of it here also.

Now, keep in mind, that the stuff used by prison guards is about 50 times more potent than pepper spray that you can buy.

Watch this and be prepared to be amazed (I would like to say that OP was the first one to be sprayed since everyone else was a bit hesitant to do so). Oh, and there is another guy that goes after OP, but you don't want to watch him...

It was a little less dramatic than you thought it would be, huh? After they sprayed him, they made him complete a set of drills- trying to show all of the cadets a situation that they could possibly face.
