After backlash, animal shelter fires security robot, “effective immediately”

"Ryan Calo, a law professor at the University of Washington who studies robotics, said that there is no clear evidence that Knightscope's robots can, in fact, predict or prevent crime. He also said that the $6 per hour fee is "arbitrary" and suggested that Knightscope may be setting it artificially low.

"They're the only game in town," Calo said. "Of course, they have every incentive at the early stages to set [Knightscope's price] low enough that makes it look like they're cheaper than security guards. There [are] often human beings that are in the background.""
