Another kind reader made a suggestion, wondering if I'd explain:
"Why do hot looking women fall for jailbirds?"
First of all, I believe your sentence contains a tautology, or at least a redundancy. I refer, of course, to the phrase "hot looking" (which, even if proper English, should be written "hot-looking"). I also object to the implicit endorsement of the objectification of women.
That said, I have no bloody idea.
I'm guessing you should ask a female of the womanly persuasion that answer, rather than an English chap who wears a suit and tie to work every day.
That said, you must have been at one (or both) of my last trials.
Not knowing the answer, of course, won't stop me from giving one: I would assume it's the classic "bad-boy" effect. You know, tough dude on his motorbike tearing up the neighborhood with a ciggy hanging out of his mouth, soccer moms throwing their underwear at him as he roars past.
I expect some clever scientist/psychologist will posit a link between the charismatic charmer and the aggressive criminal, both perhaps fueled by an excess of testosterone or possessing a particularly large 'Y' chromosome. Of course, that hardly explains the popularity of Justin Bieber. . .
Any of my female readers care to chip in with their theories?!
