This is what you do when you get caught red-handed and you have not one ounce of regret or class. 1) Deny everything. 2) Muddy the water as much as you can to try to create even the slightest, tiniest, fractional percent of doubt. Then leverage that doubt into something much bigger in the court of public opinion, where people are stupid and don't understand stuff. those tests have mercury in them and you know that mercury can't be trusted.
