how is this justifiable?

[Boanerges]

Don't forget, in that specific vid, there is as much training going on for the officer as the dog.

My speakers are broken on my cpu so I can not hear what is being said. If the officer is training then that is better then him knowing what to do already but I still think he is doing a crappy job with that technique. I should note that I am friends with K9 officers and have no problems with their techniques. I just think this guy is better suited for a different approah. More then anything honestly I wish I had not watched the video to have an opinion...

Some kids laugh when their mom beats them with a wooden spoon

Hopefully their mom learns fast that technique will not work and to try a different one
