I don't believe that Patty G was saying that rookie cops have merely taken a 12-15 week course in LE - she was saying that it is usually a 12-15 week period of "internship" with a senior officer before they are allowed to hit the streets themselves. Every state is different in terms of the amount of class course education required to be a cop - some allow associate degrees that are more specialized and may give credit for other experience (particularly if the applicant has served in the military), and some require a BS with Criminology as a major or minor before actual police training begins. There are many ways to use a degree in Criminology besides being a police officer, and perhaps Jesse realized once he was actually on the job that he would rather go into another avenue in which that degree would equally serve. (And let's not get started on the number of parents in America who have paid for a degree only to have their child either have changed their major five times or decide that the field just wasn't what they thought it would be - that's too endemic in our society to be of any specific value here).
I'm perplexed by this sudden fascination, primarily driven by the defendant and her team or sympathizers, with being suspicious or attempting to construct what amounts to a character assassination about a former fiance of KC's who, unlike KC herself, has no reputation of pathological lying, stealing from family and friends, acting wild, been observed abusing illegal substances, promiscuity, experiencing extremely dysfunctional domestic relationships, etc. In fact, of all of the people we've "met" from this girl's past, he seems to have had the most caring, honorable intentions of any of them, even offering to marry her after he found out that she lied about him being the father of Caylee. In addition, the fact that his family also opened their home and hearts to KC and little Caylee (until KC apparently decided their rules or expectations of her as a mother were inconvenient and returned home), also makes me think JG and his entire family are just very, very low on the list of potential, REASONABLE suspects here.
I am sure that every single person who knew or spent time with KC last year feels doubly betrayed by her - not only for how she lied to and manipulated them about what was really going on in her life, but for the fact that she and her family have been so eager to deflect blame in any direction but themselves that they have all had to spend an inordinate amount of time and money testifying and paying for legal representation.
It strikes me as strange that many people who have continually reminded us that KC is presumed innocent until proven guilty (which of course applies only to the courtroom), seem to have almost eagerly abandoned the same principle when analyzing her friends and acquaintances.
If we want to start looking at possible suspects (other than the only obvious one), then lets at least look at some of the shadier acquaintances she knew or has had connections with since Caylee was born and stop examining the people who are already victims of KC's "diabolical" manipulations.
