I was always annoyed that anytime I crashed my car I wouldn't see police or paramedics show up.
I also want to see security guards actually stop me (not as official cops, I mean their behavior in the class of say, your average goon - attacking you, chasing you, finding you), with the addition of security guards and cops trying to pull you down.
Similar to here:
Right away at the start of the video, the Player (who used mods to become the school Prefects.) is attempting to apprehend a fat kid.
Notice the fat kid is resisting apprehension. If security guards and cops, as well as the rare as all hell Good Samaritan can do something similar, where they will try to stop you/arrest you, and you can do something similar to resist, this would be cool.
Also, being a Good Samaritan yourself - being able to help the cops/security guards bust other evil-doers. Obviously you wouldn't be able to use handcuffs but just keeping them where they are is enough to help the cops. (pulling them down holding them to the ground or something, anything that doesn't use firearms unless the suspect is firing back at either officers or you where firearm defense is necessary. The US does this in real life, too - It's called Concealed Carry. The legal license to carry a gun for means of self-defense/defense of others who become lethal. similar to this video:
I also like the idea of, if you have a felony, it becomes permanent depending on your crime.
You should stay wanted for at least a full day on crimes such as trespassing (where security guards will often (and should) intervene on the property they're meant to patrol (like malls or parks), theft of certain vehicles (this should probably only apply to golf carts/security carts, bicycles.), riding a vehicle (motorbike, bicycle, or scooter) in an unauthorized area. (e.g, bicycling through a park that doesn't allow cyclists, this should stir up security.)
But crimes like Grand Theft Auto, reckless driving, or speeding should stick to you for a long while, until they eventually give up finding you.
This means gameplay in GTA5 will become suspenseful. You'll have to check your shoulder, day and night, change your clothes to hide yourself, hide in very dark spots, etc... for a few in-game days at most. Similar to Driver where once you had committed a crime, your felony bar would stay with you and not fade like it does in all GTAs and then boom, you're safe.
Also better police scanner lines. Here's an example:
Also watch this for a minute, has the police voices in action (from the same game the other video's voice clips originated from)
Driver: Parallel Lines cops from 1978 and 2006 also have a good example. (2006 police scanner lines from DPL are my favorite.)
You probably can't hear them all that well here, but when you do hear it, you'll get why I prefer it over GTA5's unrealistic bullshit.
There's also gameplay of DPL in the 1978 era too, which also has good cop dialogue. Thought this'd help make a good example.
