If ISIS released video like this, we would rightly call them deranged barbarians. I know these incidents may be "taken out of context", but is there a reasonable explanation for all of them (each suspect unarmed and no imminent threat to anyone)? You can see the officers have a predatory/chase mentality - they are hunting prey and need to dominate their suspects (low-brain functions vs. higher reasoning/ethics). It's not about upholding the law and protecting public safety anymore. Heck, it's not even about their own safety, as they are engaging unnecessarily closely with the suspects.  

These people are the menaces to society, not the Oscar Grants and Trayvons of the world. It's also a shame that taxpayers have to fund their salary, equipment, and pension. We are clearly not getting our money's worth. How the laws are written, it's very hard to get an excessive force conviction.

You might say, "there are good cops out there." That is true, and I hope they would be pissed to see some of their comrades behaving like this and hurting the public. I would hope they clean out the rot from within their departments. But they don't, because "the brotherhood in blue" protects its own even when fault is clear (just like other corrupt, opaque orgs like the Catholic Church). And maybe they don't enact tough police conduct laws because they don't want to be the subject of an investigation some day.

A coworker who grew up in NYC told me that the NYPD acts like an occupying army at times. This could be a reflection of that.

The Pentagon previously commissioned research into "non lethal" mass urban pacification weapons, and I guess LRAD is one of the results. I think it was originally meant for Iraq, but now they are using it against US residents and citizens, some of whom are not breaking any laws and assembling peacefully. Supposedly there are longer-term effects of the weapon, such as headaches and head ringing for up to a week. Who knows if it contributes to mental illness, brain/ear damage, or worse? I suspect the vendor and Pentagon did not really do much safety testing. It reminds me of Agent Orange in Vietnam. The brass just told soldiers to use it, and didn't know about the health risks or didn't care.

"We want to know did they have training? Do they have a written formal policy? A Freedom of Information Law request was done in 2011 and we got the results in 2012. As of then the NYPD claimed not to have any written documents."
