Tbh it’s not that hard to stop scams. Treat EVERY call you get as a scammer!
Either phone back on a known number, not some shit they give you or if they claim you need bail, ask for a reference number and the place being held and phone them after looking up the number, and If they get pissed, it’s a scam!
No real police force is going to care/shouldn’t care if you call back. It’s not like cops get a percentage of bail money but scammers always seem too desperate to get you to pay and lose it pretty quick.
