Last thing I'll say on the topic.
I can 100% guarantee that they can't track you via "legal" court approved means.
What they will do is try and scare you with threats of arrest or detainment to get you to self incriminate.
Just obey their orders but say, "I'm sorry I don't speak to law enforcement without a lawyer present. ".
If they hold you for up to 72 hours, I can almost guarantee they won't even arrest you unless you self incriminate, they will have to explain why they had probable cause to do so in a victimless, your word versus their word, case of prostitution or whatever they charge you with, and they won't be able to because if you're smart you won't talk to them without a lawyer present.
Sure there is tech I can download on my phone to track cellular signals right now, but law enforcement can't use it and disclose the use of such technology without a warrant. Now will the cops try and get you to tell them your type of car? Will they do reverse searches on your phone, sure.
But trust me when I tell you I've been through this, recently too. Showed up, woman was a plant, they tried to get me to admit why I was there, wouldn't talk to them, they got pissed off and told me to get my shit and leave after an hour of trying to get me to talk.
Just keep it non explicit in text messages and in person. You'll be fine, I didn't even miss a day of work because they knew I knew they couldn't do shit. But during that hour I sat in the vehicle, I watched them just two other guys who folded like fucking cards because they threatened throwing the book at them and they admitted they were trying to fuck chicks.
They left in handcuffs I left in my vehicle and had a nice dinner then headed to another provider for the night.
I feel like this is the conspiracy theory side of the forum all the sudden, when guys get popped for fucking ****** they got popped due to lacking the balls to keep their mouth shut and ignore the threats of the police.
They will tell you that they will let you go if you admit it. They will tell you that it's not as big of a deal or a ticketable offense, they will say that they will impound and bold your car as evidence of a crime etc etc.
Just repeat after me, "I don't talk to police without a lawyer present, am I under arrest or detained?" If they say yes, then ask when you'll get a chance to speak with a lawyer and leave it at that. They are on the clock for how long they can hold you when you're asking for legal representation and not admitting shit.
Worse case if you get the most inept police LT in the world you'll spend is 72 hours detained, and I would bet money you won't spend a moment even detained beyond the time they try to frighten you.
