I think I was watching that situation as it happened. There were a lot of "notes" being passed around I think...
It would be power gaming to just say 'oh yes, here is all the proper paperwork officer' (then RP handing them some papers).
As I understood it, they said if you come back with a google doc (something physical, with effort put in), then it is less 'powergamey', and more 'roleplay'y'...
As far as rules go, I don't see any problem unless told so by the people who's signatures you are forging. Perhaps to be safe though you should ensure you do not use their real life signature. I would be fine with this, however CMO's or CSI's here may not. Regarding the 'unlimited weed', that point means nothing. All it takes if for the cops to check their matching paperwork and low and behold, they don't have you on record because it's forged. Be prepared for quite the custodial sentence though...
All in all, I think if you put the effort in everything should work out. If you are asked to stop by CSI's or CMO's out of RP however, I would suggest you do so.
