Observe and report, and verbally harass if necessary, in an "acceptable" manner. Using robots apparently is not yet in vogue, so citizen branded patrol might be the current local-minima for this type of function: https://www.theverge.com/2017/12/13/16771148/robot-security-guard-scares-homeless-san-francisco https://www.theverge.com/2017/12/13/16771148/robot-security-... I knew someone that worked at the SFSPCA and they said the robot absolutely put a dent in car-break-ins, needling, and encampments in the animal-shelter parking lot, but advocates won in the end. What worked in Knightscopes case is the feeling of "presence" that security cams, even the panning ones with a built-in speaker, are unable to give off. So Citizen branded patrols fill that "presence" role.
