Be careful. Given that breaking news as I write this is yet another mass shooting, this time at a 4th July parade in Chicago... some of the more extreme nutjobs might take your suggestion a little too seriously.
Because quite clearly, if mass shootings are still happening, then there aren't enough guns to stop these bad things from happening, so maybe foetuses ought to be carrying? Just got to teach them to shoot out the hole, and not just aim forwards...
