Allow Police NPCs to fight a little more organized to also make them a bigger threat by giving them the ability to call for help.
Different Police types have varying degrees of funding. This will represent the tools they have available.
The underfunded cops get a whistle at best maybe 1 out of 4, It fits in with their already outdated uniform. It takes 2 seconds to use, not all have one and the range is limited. If hit or interrupted no backup will be called. It will attract any cop to the source of the noise. You can see if a cop has a whistle hanging around their neck.
Every group of Super cops has one radio. The Radio cop is highlighted with an antenna. It takes 5-10 seconds to use and pinpoints your location citywide to other super cops. That does not mean that all of them will respond. If hit, hacked or interrupted no backup will be sent. If in a group, typically one Supercop will stand back to call for backup while the others engage. It may be used to convey other information like urgency, Highcrime or Lowcrime to alter the response if those features get implemented.
Bot cops are able to transmit your location on line of sight for as long as line of sight persist. It will update your location for as long as the bot cop can see you. It Transmits city wide to other bot cops. You can only prevent backup from being called by sabotaging before engagement by either hacking, using water or an EMP.
To sum things up Police will become more dangerous in numbers. This danger scales in the types of police. However the player can avoid this by planning ahead, having good items or just good luck. That is if you plan on fighting, plan B can always be making a run before the fuzz shows up.
