I have emailed the question to someone I know, that knows someone, that knows someone.... I will post the reply when I get it.
My suspicion is, this is just a technicality..... A requirement to CYA on the state patrol's side. For example if someone lies on, or falsifies their application I would guess the fact that they signed it in front of a notary would stand up in court a little better than the clerk at the counter of NSP would......
People have a difficult time following instructions.... At every single class I teach, I instruct everyone right away and multiple times... "DO NOT SIGN THE APPLICATION, YOU MUST SIGN IT IN FRONT OF A NOTARY".... And guess how many times I have someone bring their application up and say, "Uh I guess I didn't listen well, I already signed this"
Almost every single class there is at least one.
I am guessing by requiring the application to be notarized, it is helping the clerks at the NSP office by giving them a clear black and white line...... Its either signed and notarized or its not.
Otherwise, every single day the clerks would deal with... "Oh come on, just take it, I just signed it"....... Then if there is something wrong or falsified, the clerk could not honestly testify that they watched the applicant sign it.
Heck, maybe I'm overthinking it.... Maybe there is no real good reason it is done... But I'll post the answer when I get it!
