The incident, in which the officer kicked the 16-year-old's feet from beneath him before dumping the boy to the ground, is now the subject of an internal police investigation, to see whether excessive force was used.
The teenager, who can't be named under NSW law, was arrested on Monday afternoon and was later treated at St Vincent's Hospital for minor injuries before being released without charge.
Redfern Legal Centre solicitor Samantha Lee said she found the video "excruciating" to watch.
"Not only is this police conduct unacceptable, but it is downright dangerous," Ms Lee said.
"This is a use of force in a scenario where force should not have been used."
Ms Lee said the matter could be taken up in a criminal court, or become the subject of a civil case against the police if force was deemed to be unreasonable.
She said the conduct was damaging not only to the young person involved, but for community relationships in general.
"Aboriginal young people in particular are disproportionately policed not only in NSW but across Australia," Ms Lee said.
"They are a very vulnerable crowd and it's time that this particular type of police practice is put to an end."
