The Yamuna runs for thousands of miles, and on its bank, which could be any where, the kidsplayed and drowned. So where are you going to place the gaurds?I know in the US, the life gaurds are palced in Public designated areas, but the entire Yamuna bank runs into thousands of miles, where people of a populas land play and live.Logistically its impossible in India! The mantra in India for 100s of years has been, LOOK OUT FOR YOURSELF!!!Unfortunately, it still runs true due to our huge population.
