Did you even read the LAPD questionnaire to see what kind of information they have to provide? And all of it will be verified.
Do they interview your high school teachers/administrators, neighbors, ex-spouses, childhood friends, etc. for a securities license? No, they do not. Do they perform polygraph tests? Do they have to pass rigorous physical/strength tests? Do they have to pass psychological/emotional/IQ tests? No, they do not.
And I’m not 100% sure (and can’t call any of my friends this late to check), but am 90% sure that people who apply for a securities license do not have to detail and explain every single bit of their debt and expenses — sometimes going back many years. Both might have their credit checked, but the LE hiring process is much more invasive and thorough.
