this isn't a traveling situation...
first, i live in the valley, which is LA county, the northwest end. now, my gf's stepdad got pulled over by LAPD for expired tags. he was buzzed, suspended registration, and had a suspended license. he got off with a "fix it" ticket.
today, i got pulled over by a sheriff for tags, that were 12 days over their due date (they usually don't even bother unless it's the next month). i showed them that i did infact pay their fucking dues, but i just didn't get the new tags yet. he gave me a fix it ticket as well. but now i have to go to court, pay their penalty, even though i had proof that i was just waiting on them.
the variable was that he was training someone. i overheard him telling the other officer how to call my info in and write the ticket. i guess that i was an example, so this guy could learn how to do it.
but, every other experience i've had has been with city cops. and every other one has been for no reason, or some bullshit reason. whichever case, they're still cops, and they still will fuck with you regardless
