New York Police Department retires robotic police dog

Driving the news: The NYPD revealed this week that it had ended a $94,000 contract with the robotics company Boston Dynamics for a four-legged robot that officers named "Digidog."

• Digidog had been acquired by the NYPD last August, and it had been employed in the field a few times since then, including one instance when it was used to scout a hostage situation in the Bronx before officers entered the building.
• Digidog, which is agile enough to climb stairs — a feat even the murderous Dalek robots in "Doctor Who" long struggled to manage — was meant to be used in situations deemed too dangerous for human officers.

The catch: Its presence at a hostage situation at a public housing building in Manhattan caused a fierce backlash among residents and politicians who saw it as alienating and a waste of taxpayer money.

Background: Police have used robots for decades to respond to hazardous situations, but concerns about the technology spiked after the Dallas police killed a mass shooter in 2016 by blowing up a bomb-squad robot.

On the one hand: Given that police who are under threat — whether real or imagined — are more likely to respond with violence, the possible increased use of unarmed robots might make both officers and the people they are meant to serve safer.

On the other: Taking human officers out of the equation will do little to improve deteriorating relations with the public.

• And even though Digidog was never armed, it literally does look like something out of a "Black Mirror" episode.
