Absolutely. This is not the only situation where expert testimony comes from professional witnesses who make a living supporting various hypothesis using confidently proclaimed but deeply flawed tools and analysis methods that the "expert" himself doesn't even understand. The response is that it's the job of the defense to bring up any problems with experts, but they don't always do that. It's a scam. That this is done on capital murder cases is an abomination, amoral, and should be criminal.
