You no longer need to worry about being in danger when you make the exchange.
The Madera Police Department is the latest PD to have set up a 'safe exchange zone' in its parking lot so that residents can make transactions with strangers without fear.
It's also a good place where people can make child custody exchanges.
The department's announcement on Tuesday came a week after a man was shot in southwest Fresno while handing over an item he had posted for sale on an app.
He had set up an exchange at a gas station.

Even though Facebook Marketplace, Craigslist, or apps like Letgo make life much easier, authorities say incidents like the shooting in Fresno are a scary reminder to stay wary and only meet up at safe places for exchanges.
The Madera Police Department's 'safe exchange zone' is monitored by surveillance cameras 24 hours a day.
So are the ones at each of Fresno Police's five district substations and at the Clovis Police Department.
