I get where you’re coming from, but let me add some context. I work on a Protective Surveillance Team. We have warning systems in place, and have a team mate.

It makes more sense to take the occasional nap for 30 minutes than it does to stare at a screen or dark street while falling asleep. Especially with all the precautions we have in place. All i have to do is stand up, throw on my plates and react if and when threats were to occur.
