No easy answer
Demands to analyse Connecticut school shooter’s DNA are misguided and could lead to dangerous stigmatization, or worse.
Connecticut’s state medical examiner has requested a full genetic analysis of mass killer Adam Lanza, who shot 20 children, 6 school staff, his mother and himself in Newtown in December. At first glance, it is easy to understand why. Confronted with such senseless violence, it is human nature to seek solace in scientific explanations.
This quest to understand endures as technology advances. Now, instead of looking at cranial folds and frontal lobes for clues to the massacre, geneticists at the University of Connecticut in Farmington will scour Lanza’s genes. On its own, this hunt will be about as informative as studies of the brains of murderers: not very.
The Connecticut scientists will not talk about the job they have been handed. It is not clear what they will find, or even what they should look for. Suspend disbelief for a moment and pretend that a ‘mass-shooter gene’ exists — something that no serious geneticist believes — and scientists could still draw no conclusions from a single individual’s genome.
The main point in this piece is that, while we feel technology can help us understand, a DNA sequence cannot explain anything as complex as behaviour. There is no smoking gun to be found in the genetic code that will point to a person being prone to do such horrendous acts. The risk is that we for a direct correlation where there ISN’T one. It’s far more complicated than that. The piece ends with a rational note – this may bring us useful info but it must be understood in the right context, not used to stigmatize others.
