WEST BLOOMFIELD, Mich. (AP) — More than a fifth of Detroit’s police force is quarantined; two officers have died from coronavirus and at least 39 have tested positive, including the chief of police. For the 2,200-person department, that has meant officers working doubles and swapping between units to fill patrols. And everyone has their temperature checked before they start work. An increasing number of police departments around the country are watching their ranks get sick as the number of coronavirus cases explodes across the U.S. The growing tally raises questions about how laws can and should be enforced during the pandemic, and about how departments will hold up as the virus spreads among those whose work puts them at increased risk of infection. “I don’t think it’s too far to say that officers are scared out there,” said Sgt. Manny Ramirez, president of Fort Worth Police Officers Association. “We’re in war footing against an invisible enemy and we are on the verge of running out” of protective supplies, said Houston Police Chief Art Acevedo, president of the Major Cities Chiefs Association. “We’ve got hospitals calling police departments, police departments calling each other, and it’s time to nationalize in terms of our response.” police must prepare for the possibility of civil unrest among people who become anxious or unhappy about government orders or hospitals that get overrun with patients, he said. In big cities and remote areas alike, officers are being told to issue tickets or summons rather than making arrests for minor crimes. More crime reports are being taken by phone or online. These steps to limit exposure come as police must beef up patrols in shuttered business districts and manage spikes in domestic violence.
