Known Bugs

• Sometimes a player with counterstrike skill can auto counter most enemies without pressing e to hold melee weapon... I'll try to fix it again.
  
• If you got tased and got cuffed at the same time, there won't be a timer to uncuff yourself so your teammate or your AI have to help you directly.
  

Future plan (Probably  I won't do it due to my real life work needs my full attention)

• Fixed some serious bugs. (no timer if you got cuffed while you got tased at the same time)
  
• Make it works both client-side and a host side. (Now it works only on you. Sadly)
  
• I may add an option to enable-disable this mod. (Done. Change Melee Chance to 0 and this mod won't be activated)
  
• I may add a voice line (Voice ID: "i03" that cop says "It's over", "This ends now", "Scumbag") considered it as a tuant. | Still didn't work so I'll try to fix it again. Added.
  
• If possible I may chance the lib/units/enemies/cop/logics/coplogicarrest like more than 1 cop can perform an action or when a player got flashed then cops will charge at a player to cuff him/her.
  
• Add more checking methods and functions I think.
  
• Repolish my shitty coding :P 
  
• Some other things I guess... gonna try harder with my shitty coding skill...
  

Suggestion

• Make counterstrike skill lower the chance of getting cuffed by cops
  
• Make it better :P (I'm trying)
  
• My own idea: 
  

• Stop a player from getting out of a handcuff if there is at least 1-2 cops near the player (since it makes no sense if the player can pick lock a handcuff while cops are close to them. If possible I'd like to add new animation by using a tied civ lies down to the PayDay Gang)
  
• Let cops charge at players when a flash bank exploded and cuff them. 
  
• Add a melee chance in a different type of cops (for example; medic has 50% chance, Cloaker has 75% chance, taser has 50% chance and normal cops still have 20% chance and so on)
  

• Etc.
  

Note 

• This is my second mod so as you can see, It's still buggy as fuc* 
  
• If anyone wants to help, please do since my coding skill is so fuc**** up. Send me a pull request so I can check and push it on my Github.
