Here's what you wrote:

The knife cuts both ways, Tom. If white hats can use tools like these to 
find flaws in code then black hats can use the same tools to find the 
same flaws. Closed source crypto becomes more beneficial to the world 
than open source crypto because it denies black hats the ability to use 
to these tools against it and leaves them with your once in a thousand 
years chance of accidentally finding a flaw.

Laughable, like I said.
