I would love to put the "Blackmarket checkpoint" back up but can only do so if some things are met first.
1. Approval from the commander of CFPD, Gunny. (This is first and foremost) (complete)
2. The only train checkers in Dublin would be the CFPD on duty at the "Blackmarket checkpoint". (Anyone other than CFPD enforcing anything on a cargo vessel in Dublin would be branded pirate and dealt with by the cargo ships escort or by CFPD)
3. If possible a system wide message would be sent out when the "Blackmarket checkpoint" goes active for the night and when it shuts down for the night. (This also includes a message going out to cargo ships entering the Dublin system letting them know that the "Blackmarket checkpoint" is up. Giving them time to call for "blockade runners" should they wish to smuggle BMG through.
4. Acceptance from all involved that if they are caught without Blockade runners they can either drop their 25 mill worth of cargo or be blown up if they try to run. (It would be the responsibility of the CFPD officer on duty at the gate to warn freelancers that do not frequent this forum of the impending action. Likewise mercs could "advertise" services just inside the Dublin system or in any system on the route. (Pirates, you are on your own but I know you guys can think of something I have not thought of.)
5. At the first hint of anyone getting pissed off by this, the "Blackmarket checkpoint" is gone for good. (This is meant to add something to the game not make people mad. I will stand down on the word of my commander or of any server police or by word of any of OP's Characters. So if you have a complaint you have many options and plenty of people to take it to.)
6. CFPD will be advised that if an escort is with the cargo ship, that is the first target, not the cargo ship. If the escort is eliminated then the frieghter that is running may be attacked if they have not stopped and dropped cargo. (This applies only in Dublin, if the cargo ship makes it through the gate they will be considered escaped with NO repercussion until they try to bring BMG through again.)
See you in Dublin 
7. Escort prices need to remain reasonable. I know the run to Sol is worth around 50 mil, that does not mean an escort should charge 25 mil to get a gargo ship through. I will not set prices as that will be up for the mercs for hire.
