In GTA 4 I liked beating up people, after which I called 911 to request an ambulance. After the paramedics got the people on their feet again I continued beating them up.
This does not seem to work in GTA 5/Online. Beating with fists, shooting legs, hitting with cars. Everything seems to be lethal. Still an ambulance drives up and checks out the bodies. They make some comment about the guy being dead and just drive away.
Is it possible to injure people in any way, causing the paramedics to actually do something?
