like ~bravoteam mentioned, she probably would've known their dad then. he was a detective before he was police chief and is currently retired. but the boys were probably basically always around the precinct (whichever one they worked at because there are quite a few in la). i would think it would be safe to say that everyone that knew their family probably would've expected the oldest to follow in their dad's footsteps instead of jon because he was the 'rebel' aka he just wasn't as wanting to be involved once he hit high school and i wouldn't even be opposed to saying he got in trouble but never booked because he was the son of the chief. i need to work out the timeline more in depth, but motivation has yet to strike to make that happen.
