The author seems to admit that narcotics on warrant were justified (or at least logical). I am not sure what his expectation is. Aren't you risking years of jail because of that alone? Seems wildly irresponsible if he has family and kids. On the other hand, I don't know the full situation and trying to infer information from this submitted video.
Please don't feel insulted but I feel like your comment is a result of poor civic education in America. I say that because everyone should know that guilty or not you are afforded the benefit of doubt and you should be treated like an innocent person, even if you are caught red-handed in a crime until the due process of a lawful judicial proceeding finds you guilty. This means, cops have the responsibility to behave professionally, respectfully and freaking knock on doors, avoid the display and use of military weapons, holster their weapons until there is an actual threat. Again, the lack of education in these matters is widespread, most don't know their basic rights (not just you). If you see the condtions of Jails (not prisons) in america, it is appalling, really, my takeaway is the rule of law or the constitutional rights of people are absolute jokes, rendered that way because of lack of education. To think that an innocent person with no due process or legal proceeding could be locked in solitary for months or be in an environment where they are sleep deprived and sleeping on concrete, getting raped and beat up, medical procedures against their will, losing their jobs,healthcare and housing all because the public tolerates this type of bullshit or the type of bullshit you see here where act like they're in afghanistan, because "big strong man with guns and badge good guy,can do whatever he want".
So, no, what I have seen in the video is unacceptable whoever the target is, short of an active shooter, terrorist or dangerous fugitive.
