There is no shortage of proof that police officers are working fatigued—evidenced by the sometimes fatal errors that occur as a result, reports

Some studies have shown 40 percent of police officers suffer from at least one sleep disorder and most aren’t even aware of the disorder (Shantha M. W. Rajaratnam, et al., 2011). While this staggering statistic provides proof many officers lack appropriate sleep, other empirical evidence is even more alarming.

Officers in another large study overwhelming reported that they routinely feel fatigued, drive while “drowsy,” and even have fallen asleep while driving. A recent study involving 277 officers showed that 69 percent of those studied committed fatigue-related error while working.
