If you cannot take care/train of your dog maybe you shouldn't have one. Total neighbourhood surveillance for the benefit of the 0.03% is way out of proportion.
What's the threshold for it being worthwhile to build a ubiquitous surveillance system? 365 dogs saved per year is apparently enough. How about 100? 10? 1?
I'll also note that this is just a count of the dogs found by the system, not a count of dogs that otherwise would not have been found.
And I doubt those 365 families a year think it’s useless.
