So much misunderstanding about Miranda on the news. It's a non-issue right now. Guy is wounded. You can be placed in investigative custody/detained. They probably don't even know what the charges are right now that they are going to arrest him on. Guy has to be taken to the hospital to be treated. You don't have to read him Miranda until he's under arrest and start asking him questions. Even then if the guy is talking WITHOUT being asked any direct questions without being mirandized, you can still use those statements in court. They call them excited utterances or something and courts have held that they can still be used. Example: Guy shoots his wife. Cops show up. Before he can be placed under arrrest, he starts screaming "Oh, God, I shot my wife." He wasn't being questioned and he wasn't under arrest yet, but you can still use that statement.
