The Bacterial Edit Kit is very dangerous. The sale should be controlled. Imagine if they edit the gene of a bacterium and we get a new pandemic? Only ultra-safe labs should handle this.
A malicious actor operating at scale with a lot of resources would be required, and simple educational kits like this would not be useful to them anyways. This is almost like saying educational kits for schools that contain tiny amounts of benign radioactive ore should be illegal because they could in principle contribute material for an atom bomb…
And that E.Coli strain... I believe I may have more dangerous stuff in my lower intestine.
