Assorted Callouts is now open source. https://github.com/Albo1125/Assorted-Callouts
 
Thank you @55charlie for the awesome images!
 
With Assorted Callouts, my aim is to provide a varying experience, adding a range of differently-styled callouts for you to experience. They all have one thing in common, though, and that is a fun and sufficiently realistic atmosphere!
Current Callouts (full explanation in documentation):
Petrol/Gas Theft Pacific Bank Heist Traffic Stop Backup Required Stolen Police Vehicle Person with a Knife Solicitation Organised Street Race Illegal Immigrants in Truck Store Robberies Store Shoplifting Prisoner Transport Required Hot Pursuit More to come! For suggestions and development updates, check this thread. To get early access to new versions, participate in the Loyalty Rewards Programme. Installation instructions are provided in the ReadMe.
Lots of settings, such as keybindings, callout frequencies etc. can be modified through the INI file.
Starting from Computer+ 1.3.0.0, Assorted Callouts offers support for its callout display system. For a more realistic experience, I recommend downloading Computer+ here.

Unarmed Arrests
Will most likely become obsolete when LSPDFR 0.3 is released. Enjoy while it lasts 
I've had this running in my game for personal use for a while, and I thought I'd share it with you all 
Don't like pointing guns at people to arrest them? This is your solution! With this plugin, you don't need to point a gun at someone to make an arrest any more - you can make an arrest while unarmed.
This is intended to be used with RPH 0.29. However, it also works with RPH 0.28 if you haven't updated yet.
Installation (same as in the ReadMe file)
How to make an unarmed arrest (same as in ReadMe file)
Having trouble? (same as in ReadMe file)

Foot Pursuit Aid
Please do not reupload or redistribute this without my explicit permission. Thank you.
Thank you CaptainSugarFree for creating this awesome video!
Tired of those endless foot pursuits? Do you find yourself unlawfully shooting fleeing suspects in their backs because you're too lazy to chase? This is for you.
I've had this running for personal use for ages, but seeing as lots of people were requesting something like this I've decided to share it with you.
Foot Pursuit Aid is designed to make foot pursuits more manageable in a realistic way.
When you're running, you can press Enter on your keyboard or RightShoulder on your controller to make your character sprint for a short duration. Doing this has a small health cost (but it will never kill you) and there is a cooldown of 3 seconds. This is all configurable.
Installation
Place FootPursuitAid.dll in your GTA V/Plugins folder.
Place FootPursuitAid.ini in your GTA V/Plugins folder. Adjust the settings to your liking.
Place Albo1125.Common.dll in your GTA V folder.
Add "LoadPlugin FootPursuitAid.dll" to your startup file. Alternatively, load FootPursuitAid from the Rage console (F4 ingame).

Cop Holster is an RPH plugin that adds some unique functionality to the police handgun holster. It removes the handgun from the holster if a pistol is a drawn. It also comes with intimidation mode -- a simple feature that allows you to put your hand on your holster. Cop Holster works with both the player and AI officers.
 
Here's a neat little GFY showing it in action:
 
Requirements
RAGEPluginHook 0.23 or higher.
 
Installation
Place CopHolster.dll and CopHolster.xml in your Plugins folder.
When ingame, open the RPH console (default F4) and type LoadPlugin CopHolster.dll.
 
Features
Dynamic holsters for both the player an AI officers. Animations that automatically play when holstering and unholstering. Intimidation mode, a feature that allows you to put your hand on your holster. Toggle with Right Shift Key (keyboard) or Left DPad (controller). Highly configurable! Turn off animations, change keys, add new ped models for Cop Holster support, you name it.  
Questions
Does this come with RDE support?
The RDE Cop Holster config file is in the RDE 3.1 download.
 
Does this come with EUP support?
Yes. Cop Holster comes with support for EUP 7.5.
 
How does Cop Holster work?
All ped models in GTA have what are called drawables. They are pieces of clothing or equipment that can vary between instances of that model. Many of the default cop models have two holster drawables. One is empty, and one has a pistol. Cop Holster simply changes between those two drawables depending on if you have your pistol drawn or not to give the illusion that you are taking the pistol out of the holster.   

I'm a ped model developer and would like to make my model work with Cop Holster. How would I go about doing that?
See the readme in the download.

Either myself or someone else will be more than happy to help you out!

If you are installing LSPDFR 0.4 for the first time, we strongly recommend that you do so on a clean copy of Grand Theft Auto V without any other mods or plugins.
 
LSPDFR 0.4 brings sweeping changes which have been implemented over a number of years and is the latest major version of LSPDFR, released in December 2018.  LSPDFR turns the world of GTA V upside down, giving you the power to enforce the law as you see fit.
