nico,
even kws on their game walks might run into game which is by far not predictable!
we cannot predict our very own cat or dog - how can one predict the reaction of a wild animal?
for example in botswana they take you for game walks to chief's island (okavango delta/moremi reserve) which is quite adrenalin driven exercise: so we get off the boat which took us from camp to chief's island and............walk and see lion droppings, elephant droppings, buffalo droppings.........and we walk single file as requested and OOPS all of a sudden when we passed dense bush area we heard this cracking......... there were elephants we almost ran into the huge masses.........stood still immediately and retraced slowly but surely .........our guide had nothing to give a warning except his voice.........(guides in NP are not allowed to carry weappons due to botswana law!)
we got back to the boat and when we were talking about the encounter there were 2 lionesses walking the water's edge a mere 50 m where we just embarked the boat after the walk
a second incident was in greater krueger NP where we were after white rhinos which we found also after passing dense bush area in the open. 2 of them were munching but all of a suddun the stopped eating, lifted their heads and were looking into our direction. of course we were wlking because we wanted to see something.but when you are that cloese to these powerful animals you immediatly realise your adrenalin is pumping up to your fingertips and lift is pretty vulnerable and depending on these creatures moods.....
despite never being charged on foot i doubt the whole game walking idea is a good one. live and death might be a matter of seconds. and quite frankly i don't want to become a reason for enhancing the safety measures!
if a lion/tiger develops an appetit for human flesh is another question.............
as i don't differenciate between animals and human beings (which are also animals if not the worse) i would say it might be killed if it's for certain that one particular animal has become a man-eater. but i oppose the killing of lions or tigers at random - which did george adamson when he was looking for a lioness which killed but did not eat its prey - when he killed elsa's and her siblings mother!
