My question involves criminal law for the state of: PA
My son was in backseat of parked car when an officer approached the passenger who was drinking out of a red plastic cup. I think he thought it was alcohol, but it wasn't (it was the mountain dew he WAS chasing the alcohol with). After realizing it wasn't alcohol I guess, he assumed they were up to no good so began asking questions about what looked like grass remnants on the seat/floor and asked to search the car. The driver replied "no". He ordered the passenger out of the car and found a .01 with breathalyzer. He than ordered my son out of the backseat and noticed the marijuana bag (Very small amount in a bag) when he got out laying on the seat. He than impounded the car. My son took responsibility for all the marijuana. He then confided to me that the front seat friend has a pipe in the glove compartment. My son honors student headed to college in two weeks as a education major. I contacted a criminal lawyer and waiting to hear back from him. What is biting at me is did that officer have probable cause to yank my son out of the car and find the pot?
