Not sure where to start...

The boy friend is in a spec of trouble.

we were pulled over had our vehicle searched and they found and are charging just my bf with trafficing cocaine 16 G.
The 16 gs where brought for his brother in law which IS in trouble and needed to RAT people out in order to get out of trouble him self, so therefore we have found it to be 100% true as per his sister (which the brother in law doesnt know that we know it was him) that he is the one who set up the drug bust when mean while they had no other reason to pull us over other then some one notifying the police that is why they had probable cause for pulling us over.
going on this the court date has already been remanded 10 times because the crown will not disclose WHO this person is that gave them the probable cause to pull us over, they have now set a court date for this Thursday which still havent giving discloser and wanted to come to an agreement.

sense there is no prevoius charges, + wondering if they HAVE to disclose whom was the informant in court to make it legitimate charges or even though they didnt have probable cause to search the vehicle they did find some thing. Just wanting advice or an oppinion if we have ground to possibly beat the case or if they drop it to a Posession charge if it would be a smart idea to take that.
