If you think that you’re seeing more police officers on San Francisco streets these days, you’re right.

There were no less than four teams of two to three uniformed police along Market Street, from Civic Center to Fifth and Mission the other day.

“We’re from investigations,” said an officer standing with his partner at the corner of Seventh and Market, next to an gray, unmarked police car parked on the sidewalk.

The heightened police presence can be seen throughout the city, particularly along commercial corridors.

“A few weeks ago the department reassigned some sworn members from administrative and investigative positions to uniformed patrol assignments,” SFPD spokesman Michael Andraychak said.

Ten sergeants and patrol officers were temporarily assigned to district stations from administrative and investigative units. Thirty other sergeants, inspectors or patrol officers are assigned to districts on a daily basis to support field operations, Andraychak said.

The increase in police presence on the streets also increased the risk of the officers contracting the virus, a concern of the Police Officers Association.

“We got ahold of 150 gallons of sanitizer in case any station runs short and we are talking with a person who wants to donate 75,000 face masks,” POA President Tony Montoya said.

“So far we have been really lucky. Only two of our members have tested positive,” he said. “I don’t do it very often, but I’m giving a lot of praise to Mayor London Breed for acting as soon as she did and following through to keep our officers safe,” Montoya said.
