No server rules or police rules have been broken here. You got screwed by the helicopter that landed. You can't expect the police to ignore a helicopter landing near the drug dealer. Also the camping rule goes out the window if you have some reasonable cause to go back. It would give people a 20 minute window every half hour to run as many drugs as you want.
I have said it before and I'll say it again. Be smart when you run drugs. If you are going to do it alone you are gonna have a hard time. Get a few scouts, armed if possible, and keep an eye open for any police. Cause a distraction or something. Do not whine and expect comp when you are caught red handed.
