It should provide actual evidence, or evidence to the contrary, that the police in NY are murdering people on a regular basis as a matter of policy. All of the footage of police not murdering people is of value as well, after all.
You moved the goalposts on someone else's assertion. No where was "on a regular basis" stated except by you. The recent chokehold death - a banned technique that resulted in a death - is a good example of what the parent was probably talking about.
Fair enough - I didn't mean to imply it on the part of the parent but on arguments about police brutality in general, particularly on the internet.
"are murdering" implies that it continues to happen on an ongoing basis. "on a regular basis" is moving goalposts, but not moving them very far.
"The ny police is murdering..." doesn't make much sense in English. And it has happened more than once. The other time I can think of is when they killed the guy in times square.
The difference between "murdered" and "is/are murdering" is that the "murdering" implies that either it is happening at this very moment (which is clearly not the case here) or it happens on an ongoing basis.
The question is not whether any one lapel cam video might result in action where various random cell phone cam videos have not, but rather, how many such videos in how short a time frame will result in action? If the evening news had a 20 minute montage every night of the days police abuses, people would be calling for Bratton's head on a pike.
