"People who are taking the side of the stray dog - Can you guarantee that no stray dog in New Delhi will ever do the above to a small child in New Delhi or elsewhere?"
Nobody is taking any sides. It is question of choosing between a human, compassionate approach and a irrational approach based on blanket fears. A certain amount of healthy fear is reasonable, and dogs, especially unfamiliar ones, should be approached with caution but an idea to masacare the entire population is far fetched. Even if you kill all dogs in your locality, within few weeks new dogs from neighbouring areas will come again as the "territory" will become free for them to occupy. Even if you kill all the dogs of Delhi, within few weeks dogs from neighbouring places outside delhi will come in. As far as your persuit of "guarantee" is concerned, nobody can give any guarantee for anything in life. Niether is your approach any kind of guarantee for anything.
"The best method is fast. Efficient. And permanent." Your method is by no means even near to being so called fast, efficient or permanent. You kill all the dogs in your locality, within few weeks new dogs from other localities will fill the "territory" held by killed dogs.
"And does not put a burden on the tax payer." The recorrent cost of killing is actually a big burden on tax payers. After all they are living eating the garbage and filth of your locality, how are they burden on you or society?
"In a society riddled with bankrupcy and so many serious problems, we are actually wasting money and resources on keeping stray dogs alive? Amazing." It is really amazing how the dogs are causing bankrupcy or corruption in society? Something really wrong in perceptions and thinking of people who find that dogs are causing bankrupcy and other problems like corruption. They are living eating the garbage and filth of your locality, how are they causing bankrupcy or corruption? If you can't fight bankrupcy or corruption, why divert your anger and frustration towards helpless creatures? It is only the rich and elite(or neo rich and elite) who feel that their status is getting belittled by "presence" of dogs in locality find them a problem. Poor people and their children can happily co-exist with dogs in their localities as friends.
"Whether the child provoked or didn't provoke is just not relevant. You can't control a 6 year old. Nor can you watch him 24 hours a day." It is a tendency of not taking responsiblity for your children and putting the blame on others. It is no wonder that why children these days are also taking to crime, drugs, illicit s*x etc. and parents rather than taking responsibility, find it easy to put the blame on something else.
"I am sure there are better ways of guarding the neighbourhood than stray dogs." Even many gaurds themselves feed the dogs at night because they help them by giving early warning better than anyone else. No human gaurd can match the night vision, hearing capability or sense of smell of dogs. Even our security force personel in disturbed areas feed the stray dogs around their posts and camps as they provide an early warning of unwanted people before any human can detect.
