N-ways to get away with it if police finds out

[Foreversad]

Im studying the possibility of n .the problem is some members i had a chat with are afraid of the police as i do also. I think these are rare occasions but i had a research and found out about 3 members that had police in their door.so lets see... If we seem unlucky and they find out from what i read we can deny if its on customs and if its sentand we receive and police comcs by afteer a good trick is to not open the parcel and place a paper saying 'return to senter'. So that we are free .the thing is how can we keep it and still get away with it ? Some members say hide it.yeah ..ok ..but police is nasty they will know we went to the post office and received the parcel .so ..please any ideas ? As some of us are afraid .any ideas?
