This is going to sound snarky, but there is an obvious difference in how this guy is being searched for than other killers.
Remember a couple of weeks ago when there was a manhunt for the guy who sent the manifesto to President Trump? What, it took 24 hours to find him? He also talked about various groups so LE wasn't certain what his intention was.
Or if an LE is murdered, it is a full scale manhunt to locate him. Now with several LE murderers in recent memory they have been skilled and managed to elude police for a time. However, there was still a manhunt going on.
The point being this guy walked up to an unknown man and shot him. Yet he had the foresight to record his actions live on FB. Is he not one of the scariest people to be free on our streets? Where is the manhunt for him?
Are we the citizens not just as important as the above examples? Are we waiting for him to strike again to get his location?
My opinions only.
