My question involves criminal law for the state of: Pennsylvania/New Jersey

Make this quick and bearable:

On Probation for a year, 1 month in.

I left state of ( PA ) and went to ( NJ ) this weekend 5/4-5/6.

Today Sunday me and my 3 friends got pulled over ( I was a back passenger )

They, Asked for our ID's and went to their cop car. They took my friends weed (1 gram) and let us go, no Ticket given( THANK YOU!!!!!!!!!!!!!!!! NJ!!!!!!!!!!!!! )

now i KNOW i should DO THE RIGHT THING and tell my p.o. but On my Mothers Grave, this lady is really mean and miserable person ( PA p.o.)
im not the person to keep things from my p.o. because thats just not right, but guys im 90% sure she would make me go to jail.

The whole point of all this is, *** WILL SHE KNOW!? ***

I LOVE AND APPRECIATE EVERYONE WHO EVEN TOOK THE TIME TO READ THIS, PLEASE AND THANKS FOR THE COMMENTS, IM SCARED =(
