Snapchat question..

Tonight, I observed my daughter using Snapchat and asked her to show me around. If you're not in "ghost mode," it appears that anybody can see your images here, and it even displays a large circle on the map to represent your position. I immediately began to consider the issue of Abby and Libby. I'm interested whether the FBI has access to the number of people who have seen their Snapchat storey. Due to the lack of proof for a warrant to expose the users' information, this connection makes me wonder if the investigators would have access to only the girls Snapchat and not anybody else who watched it.

Law Enforcement on Snapchat Is it conceivable that these ladies were seen on a Snapchat map by a stranger who knew he had plenty of time because of how far down the route they were? Please accept my apologies if this has already been addressed. Every year, my heart breaks for them. Thanks!
