On second thought, I'm not going to offer a free lesson in law to dumdums that choose to be ignorant. It's my day off and talking to a brick wall(s) isn't how I plan on spending it.
Based on what is reported: There was reasonable suspicion for the stop. There was probable cause for the warrantless search of the vehicle. The occupants of the vehicle were lawfully detained. There was contraband located in the vehicle. One subject was cited and released. Pretty damn simple.
Lets just get down to the foundation of the argument here in the original post.
1: Marijuana should be legal
2: I don't like cops
The truth shall set you free!
