The police spawning in out of nowhere reeks of some idiot managerial/stock decision so it 'feels' like GTA to the normies so they buy it. Its completely unacceptable in terms of mechanics or lore.
Commit multiple incidences of first degree murder in broad daylight on a crowded metropolitan street in a rich neighborhood because you're employed as a contract killer with a heavy machinegun, illegal cybernetic implants and highly lethal cybersoft that can fry a person's brain and force their implants to emit toxic chemicals that are transmissible in the air? Fine!
Accidentally ram a fat hobo with a van at 5 AM on a desolate waterfront in the worst neighborhood in the city? WE'RE SENDING 50 TACTICAL DRONES AND 200 OFFICERS FOR THIS SENSELESS LOSS OF LIFE!
It is so retarded that someone had to have seen this but it was overriden by some idiotic middle manager type worried about stock numbers. There's no way anyone can look at this and got 'this is acceptable and doesn't break immersion or will look horribly incompetent'. It is there because they wanted a GTA system for idiots and by God, they would have one, no matter how fucking stupid it was.
