I'm probably missing something obvious here, but is there a reason the article mentions this is regards to the Sandy Hook shooting incident? Because there aren't exactly any features here that would have helped much in preventing it, unless you think detecting the shooter's car by the numberplate is somehow going to have made a major difference. If they really wanted to stop things like school shootings and terrorist attacks, then the robot needs to actually be armed in some way, since no one is going to take this thing as some sort of deterrent. Really, it seems mostly useful as a sort of tourist attraction rather than anything more, since it's apparently really popular with the people visiting the mall.
