Isn't it at the Caymans that they have sting ray alley where people go to swim with hundreds of sting rays at a time? If they were so deadly I doubt it would be such a booming business.
The fact that people are able to let their stupidity overcome their common sense dosent make something safe , The fact that 100,000 people a year are willing to skydive out of a plane dosent make it safe , So really saying because lots of people are doing it makes it safe is just to cover up the fact that it is in fact stupid and dangerous.
