Entrapment is the process by which police ask or induce you to commit a crime. For instance, if a police officer gives you 20$ to assault someone, then that is entrapment. However, if the police simply stand on a likely corner and you assault them, or ask them to buy drugs you are boned. Same thing if you steal a bait car that is left running with the door open.

This is kind of like leaving a bait car parked and running with the doors open. Oh look I'm a child online! This is what I look like. They cannot attempt to seduce the pedophile. However, they can let them do what pedophiles do. Then, when the pedophile makes an attempt to meet with the "Child" they can arrest them for attempting since they have demonstrated intent and action to make good on that intent.

In this case, they do the same with Snapchat.
