EMS worker stabbed in Middletown

my question is how do you know it is a police officer that is stating these things, found you on facebook and doing things to you? Not arguing just asking. Alot of people get on and pretend who they are. It is not only police who can use the internet to find things out about others. There are many sources for information from our fine goverment that anyone can get to to find out personal information about others with very little trouble.
