That's correct thats why they had trouble pinning anyything on him, if the accused(according to his testimony) just shrugged off a taser and knocked down a cop, adrenaline will kick in and you'll use enough force to make sure the accused stay down. Though with body cams he implied they'll just ignore possible criminals as they'll be judged unfairly for protecting themselves from harm.

Article doesn't make clear if arrests were justified or not(false arrests, cop planted evidence on victim etc). Excessive force is able to be excused away by saying he was apprehended violent criminals who were resisting and even knocking out cops which the article supports his statements. Article is a little odd as it seems to provide more evidence to defend/justify his position

To be honest the article doesn't clarify if he made false arrests or other than the protesters(not states if it was the throw stuff or charge at copy's type) beat people that weren't resisting. Not that excessive force is justified but if he's able to prove it's mainly in the heat of the moment where the suspect is violently fighting back in dangerous neighborhoods I can see how they can't find justification for harsher charges.

Aren't bodegas supposedly major offenders for fencing stolen goods from pharmacies and big box stores?

Correct there's no violations of any US laws hence there's no grounds for charges so they can continue to operate. As you can see from the articles they're operating in broad daylight and have been careful.

They're probably working for a company not directly for the government. All countries have companies operating in other countries that are basically serving their home country's interests, plausible deniability. Pretty common plot element in spy movies

They're not enforcing foreign laws on us soil they convince people to return to China where they then can enforce laws. It's like the spy movies unless they're caught doing something illegal in their cover, cant arbitrarily detain or arrest people.

I think it's like the old stories of a private investigator firm in another country. I think I read that in the US the FBI monitors them but unless they break any US laws or the people they're persecuting file charges they can't do anything.
