Your analogy also isn't the best because it heavily suggests the nefarious behavior is easy to identify (throwing people off a bridge). This is more akin to people helping those in need to cross a street. At first, it is just people helping people. Then, someone comes along and starts to "help" so that they can steal money (introduce vulnerabilities) to the unsuspecting targets. Now, the street-crossing community needs to introduce processes (code review) to look out for these bad actors. Then, someone who works for the city and is wearing the city uniform (University of Minnesota CS department) comes along saying there here to help and the community is a bit more trustful as they have dealt with other city workers before. The city worker then steals from the people in need and then proclaims "Aha, see how easy it is!" No one is surprised and just thinks they are assholes.

Sometimes, complex situations don't have simple analogies. I'm not even sure mine is 100% correct.
