A police officer is approached by a man on the street who tells the officer that he was just robbed?

Question

...  The man points out the robber, who is standing in a park just across the street. Must the officer obtain a warrant to make the arrest?

Answer

Police only need warrants to enter private residences. 
Warrants take a long time to process. By the time he gets the warrant, the guy that robbed the other guy could be gone, and the warrant will be pointless.
