Where's the information leading you to believe he was a drug dealer? And how is it a guarantee that the was killed due to that status, even if true?
Your second point seems to support my speculation that his murder was somehow connected to his role in the trial.

"“Thaddeous Green was the facilitator. He’s the one who contacted Joshua Brown,” Asst. Moore said.
Moore said when they got to the location, “Green gets out of the vehicle, has a conversation with Joshua Brown which escalates into physical altercations.”
Jacquerious Mitchell told police when he got out of the vehicle, Brown ordered him to get back in his vehicle and shot him in the chest, Asst. Chief Moore said.
Jacquerious Mitchell said while wounded in the vehicle, he heard two more gun shots.
“He said that Thaddeous Green shot Joshua Brown two times,” Asst. Chief Moore said.
Green also took Brown’s backpack and gun.
Michael Mitchell was the driver.
Police said he dropped Green off to an unknown location and took Jacquarious to the hospital. He is currently in police custody at Parkland Hospital.

a hospitalized suspect from the shooting says he and the other two suspects met joshua on a drug deal. brown had 12 lbs of lettuce in his house.
sure, connected to the trial, in that criminals who potentially wanted him dead now knew exactly where he lived.
that does not at all support your speculation that "no, a cop didn't do it. but someone sympathetic to them may have."
