Some local police departments take time every day to check certain groups on Facebook and profiles of known criminals. Police say you can also do your part by keeping your eyes open for suspicious activity and reporting it to authorities.

It's a world wide web of drugs, human trafficking, and more. Criminals are using Facebook, Snapchat, and other websites to communicate. Those sites are a prime place for drug dealers and prostitutes to find customers and arrange to meet up.

This has been happening all throughout our area from Gates to Canandaigua and beyond. So what does law enforcement do to crack down on this issue?

Investigators have methods that can't be shared with the public, but we can say it's a constant game of thinking like a criminal.

Officers log on to the popular social media sites with undercover accounts. Criminals often try to offer those accounts drugs or sex.

Using this method, Gates Police Officer Lance Duffy say they have stopped planned fights and drug deals and busted prostitutes.

"We realize that it is a great tool, but by the same token when something really great comes out criminals learn to adapt to it and use it," Duffy said. "Our main concern in this is the children, obviously. They're on social media 24/7."
