For this achievement you need to get a gold medal in all cop events, in order to do this you must be a fairly good at racing games, you also need lots of patience, You may need to try a event 10 different times to complete it.
Here are some tips to help you...
1. Rapid response missions: very frustrating at times, i recommend you pick the fastest car you have, and the one that has the best 0-60 time. All the cars handle different if you cant complete a event in 5 attempts, then i suggest you pick a different car. Because even though they are not the fastest car you have, some will drift better. Also i recommend not always drifting corners. Drifting will slow you down, if the corner is wide enough to not drift then just turn around the corner instead of drifting.
2: (Interception missions) In this mission it is a 1v1, you vs a ai opponent. These missions will require you to take down the enemy before a certain time to get the gold medal. The best thing to do is drive up next to them and slam them, the best time to slam them is around corners. If you slam them and you get ahead use a spike strip to do extra damage. If you are behind them use a emp to shoot them, but be careful they may drop skipe strips and hit you. When using the emp stay a good distance from them so you can swerve to avoid the spike strips if you need to. If you are super far behind and cant catch them you can use a roadblock to slow them down. You can also use the helecopter to drop spike strips in front of them. But make sure you dont run over the helicopter spike strip, it can damage your car as well.
3. Hot pursuits: in these missions you have to chase down large groups of street racers. You have to destroy all the racers before they get to the end of the race to get the gold medal. The best strategy is to hit the racers at the back and take them out by slamming them, also call in a roadblock every once in a while to stop the guys at front from getting to far away. I recommend saving your emps for the last racers because they are the fastest and hardest to catch. You can use skipe strips for the racers that you spin out but dont take down, when they get close to you again drop a skipe strip and take them out. You can also use helicopters to help damage and destroy racers. The helicopter goes for people at the front, so when you are down with the guys near the back, the guys up front will be damaged.
