This is not a good practice as it gives people too much of a comfort zone around animals which leads to incidents such as this.
This is not the fault of the animals. When they attack humans, they are only acting on their instinctual impulses to defend themselves. Even your own domesticated dog will bite you if they feel threatened. People should be intelligent enough to give all wild animals a respectful distance.
Many people think "Bambi" is a nature documentary. They really ought to see "The Ghost and the Darkness" for an antidote to this silly sort of thinking.
