Do Animal Control Officers Use Excessive Force On Dogs?

I have a pretty long history of animal welfare promotion. This latest story is out of Beaumont, CA... 

There have been verified stories of abuse by animal control officers across the country. Sometimes they get fired, sometimes the problems are covered up, which is easy to do in government controlled animal control shelters. 

Here is a current video of an animal control officer using a catch pole to lift a pit bull off the ground and toss it into the van. There is more to the story, so it is worth reading. 

What is your opinion? Especially if you have knowledge of this situation?
