Shocking crimes by all involved but I fear that nothing will really change until the authorities in the eastern countries ( where 99.9% of the horns end up) tackle the problem first hand. Much stronger penalties and prison sentences need to be put in place as well as a massive educational program to make these people aware of the dire situation here regarding these animals.
I dont think that the authorities there really care about an animal that comes from an ocean away.
Regarding the local's who orchistrate and carry out these deeds, consider that even the kingpins and top guys who arrange this type of thing will if convicted most likely only get a fine or a term not exceeding 10 years. Of those ten years, they might only serve 4 - 5 years in jail. These @#%$! have made millions off their crime and to be honest I dont think they are too worried. Their lawyers will prob plead guilty to a lesser offence and they will walk away with a fine. R 250 000 maybe? Wow, thats like one or two rhino horns! Out of 200 plus that have been poached. There's your problem Sherlock! You will never ever stop the carnage until the punishment becomes more of a deterent. Eg R5 mil fine and min 25 year jail sentence i think would be a good start. This I'm sure will at least give these animals a chance.
The biggest problem however still remains the fact that the eastern countries do very little to change the attitudes there, and while there is a market, there will always be a supply. No matter how bad the consequences if caught here.
Dont be suprised if within the next 20 to 30 years, the only place to show your kids/grandchildren a live rhino will be at a zoo or on You tube.
