Yes, that is a good tip. I encountered the same thing. On patrol, a world event pickpocket came up so I chased the guy and pulled a gun on me. Had to shoot him and then all of a sudden, two other guys came around the corner shooting. If you don't know the bad areas of the city, I recommend downloading the crime chart. You can pretty much tell by the neighborhood where the bad areas are but crime chart helps.
But on topic here, Abraxas, I didn't have the latest ScriptHook which I thought I downloaded that a while ago and installed but it works. I got to play for about a hour before it finally crashed (LCPD:FR crash not script). I love the world events, makes things really more realistic than seeing a cop chasing a guy without knowing what's going on. During the time played, I had a head on collision, car fire, shooting, fight, pickpocket, reckless driver, speeder, and carjacking. Few pursuits entailed so it was a awesome gaming experience. I did test the call services buttons (coroner, tow truck, and fire truck). All work perfect and handy. I just couldn't get fire to my location in time to save the car from exploding. Other than that, awesome job and if I find any bugs, I'll let you know if they're not already reported.
