Just over a year ago, a 60-foot dam broke in a power plant in Tennessee, dumping more than a billion gallons of toxic coal ash into a nearby river and community in Roane County.

But the Tennessee Valley Authority, the federally owned corporation that owns the power plant, has insisted that coal ash is no more toxic than dirt. And it has done nothing to clean up the spill.

Meanwhile, residents report a wide range of health problems, including nose-bleeds, coughs and headaches. And the arsenic, lead, mercury and selenium that have been found in the coal ash has previously been linked to cancer, liver damage and nervous system disorders.

Last year, 60 Minutes did an extensive segment on the disaster and the failure of the Tennessee Valley Authority to remedy the situation as well as its denial that coal ash is toxic.

So in comes the United Mountain Defense, a civilian activist group that is striving to help the residents of Roane County by collecting data and samples in the area to be tested.

Last year the group was invited on the property of one of the residents to test the air with air monitoring devices.

Within minutes after setting up the air monitors, police officers from the Roane County Police Department as well as the Tennessee Valley Authority swarmed on the property and began hassling the UMD members.

At one point, as can be seen in the above video, a cigar-chewing ignoramus of a cop demands to see a picture identification of one of the UMD members. The UMD member hands the cop a U.S. Passport, which anybody with any sense knows it is an acceptable form of identification anywhere in this country.

But the cop acts like he has never seen a passport before. And he continues to demand “a picture ID.” When informed that the passport is a picture ID, the cop then demands a driver license. But the man tells the officer that he is not driving and that the passport is a valid picture ID.

The cop, whose name is Robert Childs, according to a comment on the Youtube video, then snatches the man’s camera and orders the air monitors to be taken down.

The situation was apparently resolved by another cop who doesn’t come across as abrasive as Childs, telling the UMD members that they have “been nothing but peaceful to us.”

The cops eventually leave without further incident.

If anything, the video shows a startling contrast between police personalities.

On one hand, you have the abrasive sonofabitch who escalates a peaceful situation and appears to have an IQ of an ant. And on the other hand, you have an officer who at least seems to have a sense of professionalism and basic people skills.

If if weren’t for that officer, no telling how that situation would have turned out.
