“He was also charged with possession of a firearm as an ex felon and possession< of marijuana.
Did those charges stick or were they dropped too?”
Remains to be seen. The issue will boil down to whether it was a reasonable search and seizure. Was there probable cause for the search of someone changing a tire roadside? If not, then he walks.
The position of marijuana is the only one officially remaining.
The charges were not officially "dropped" but they did vanish like the summer snow because the man was not a felon. So that means they can not charge him with being a felon in position of a firearm because not a felon.
Apparently with her other problems Super Cop has a problem with telling the truth.
