Many ways to be bad to other people if that is the intent. Hammers, chainsaws and bread knives are still sold freely though every day, so lets not get into Hollywood hype style overreaction.
And please do not mention insulin in this connection. Would like still to bring it with me in public, and not have to go to a locked-down security office to get every shot I need. Hollywood has already overused the diabetes plot, and still continuously gets the disease and dynamics completely wrong. They must be running desperate low on better ideas.
