It does.
First, there is no "trend"--a direction in which things are changing or developing--at least not based on what you've written. [So there has probably always been a correlation between non-violent people and levels of education.]
Second, writing that "education . . . reduces substantially your tendency to commit all types of crimes" mistakes causation for correlation and writing it like that obfuscates the very real possibility that it is a selection issue--that is, that people prone to crime for whatever reason don't advance in the education system as much as those who are not so prone. [So Ivy educated people are, in fact, less likely to be violent criminals, but not because their Ivy League education made them that way --it's because non-violent people flock to Ivy Leagues and Ivy Leagues select for characteristics that are contra violent behavior.]
Both of those points are inconsistent with the notion that a college education could be used to radicalize people in this direction or that that is some kind of new phenomena.
But if you need me to say it more explicitly, I will: I don't think wealthy people attending Ivy League schools are being turned into violent actors by their professors. In fact, this guy was an engineer, right? Engineering profs are going to be, on avg, some of the least radical profs on campus.
