The need to dehorn captive rhinos

If we ever needed a reminder about how dire the situation is with rhinos the recent shocking attack on a captive rhino in a French zoo surely shows us. It was a new low in the ongoing rhino poaching crisis that Vince a 5 year old rhino was shot and his horns cruelly removed. It is hardly surprising to learn that a zoo in the Czech Republic has taken the drastic step of dehorning their rhino population to thwart would be poachers from doing the same thing there. Can it get any more tragic for rhino that even the captive ones are not safe from the greed that would tempt poachers to enter a zoo to kill an animal for profit. Perhaps the penalties for attacking a defenceless animal in such a callous way needs to be upgraded in line with the penalties given if a human being was the victim assuming every effort was made to catch the crimminals.
