@Cloud_Power Just wanted to call your attention to Better Chases + Arrest Warrant :P
Create your script anyway - Just make sure it's compatible with Eddlm's mod.
Also, as soon as the police forces are authorized to use Deadly Force, looks like it's impossible to surrender on foot. Maybe you can make that possible as well?
Apart from that, @HeySlickThatsMe's idea suggestion sounds like a really cool idea.
I would love a destructible city via nuke mod. It could be done by activating a nuke and once the nuke explosion ends the mod teleports the player to a dessert location with loads of molded building rubble every where. If timed right it could look like the city has been vaporised
